I used Google Chrome in Windows, and am now using Chromium in Ubuntu. Is there any difference to the two programs? What are the advantages and disadvantages to each program? Which one seems better?

There are some key differences between Google Chrome and Chromium. First off, Google Chrome is a commercial closed source product made by Google which is based on the open source Chromium project.
Chrome is not available in the default Ubuntu repositories as it's not open source, however Google makes Chrome available through their own 3rd party repository. Chrome is updated by Google directly, as they run the entire repository and update Chrome on their schedule. Since it doesn't need to be redistributable and open source, Chrome includes things that we can't ship in Ubuntu out of the box, like Flash and H264 support (See the Ubuntu promise). However you can install this support with a few packages (see below).
Chromium, being open source, is available in the Ubuntu repositories. This is maintained by Ubuntu developers and goes through our Stable Release Update process. Chromium has a release process exception, which allows the team to upload a Chromium build as soon as a new upstream release is made.
There really aren't any proper "releases" made of Chromium, so Ubuntu developers base their build on what stable version of Chromium the stable Chrome build is based off of. Fabien Tassin has a blog post about this process that goes into much more detail.
The following packages in Ubuntu install the codecs and features in Chromium that you can find in Chrome:
chromium-codecs-ffmpeg
chromium-codecs-ffmpeg-extra
flashplugin-installer
Really it depends on what you want. If you trust Google to not break your computer and like the convenience of Chrome then you can use that; if you want an open source browser that is the basis of Chrome that is peer reviewed by Ubuntu developers and doesn't require 3rd party sources then you want Chromium.
This Wikipedia page outlines some of the security/usage tracking differences between the two browsers.
The official Chromium Wiki provides a detailed list about the differences between Google Chrome and Chromium. It does not reflect differences of vanilla source versus those that are specific to Chromium packages provided by Ubuntu.
Google Chrome is based on Chromium, the Open Source Web Browser. I've been using both of them and they are 99.99% similar. I finally choose to use Chromium because it's open source. You can still use all the extensions for Chrome, and also sync your bookmarks (and other stuff) with a Gmail account.
If you look at Wikipedia it says that the differences are that Chrome has Adobe Flash Player pre-installed (not open source software) and Chromium not. But you can still install it later very easily. That Chrome has auto-update mechanism, but using Ubuntu you have auto-update (and you can also add the Chromium repository). Also that Chrome has Google's brand and Chromium not (I don't care) and they say something about the colors of the logo (not very intelligent comments). Finally they say that Chrome has click-through licensing terms and usage-tracking. This last thing I'm almost sure is optional.
Use Chromium!
There may be additional differences, but the biggest is that Chrome is not FOSS, Chromium is. Chromium also lacks the built-in flash plug-in, though I understand that it will pickup the normal plugin(ffmpeg) without issues.
Chromium is the bleeding edge development of the project. It is the browser, and whatever its current state may be. We usually get a few Chromium builds per day.
Google Chrome is simply a re-branding of Chromium, but is a little more ready for public consumption.
There is another major difference chromium is with usage tracking, like link posting from wikipedia:
Google Chrome is the end product designed for everyday use. Chromium is an opensource project to develop the code that runs Google Chrome.
One thing to note, Google Chrome releases obtained via Google officially should be stable whereas code from the Chromium project is cutting edge and likely to be buggy.
If you want a browsing experience that isn't riddled with bugs, go for Google Chrome. If you enjoy browser crashes and Flash memory and CPU usage being through the roof, you clearly need the bleeding edge untested code direct from the chromium project.
At Last we have to understand that, whether it is Chrome/Chromium/Firefox/ Google probably doesn't care which web browser you use. Google wants this internet eco system to grow and that is where their money is.
Chrome blocks extensions outside the Chrome Web Store; Chromium does not.
Chrome includes tracking features such as RLZ; Chromium does not.
Chrome's EULA used to include the following:
This has been corrected, whatever that means. Whether this point matters though is debatable; after all, if you have nothing to hide...
Finally, Chromium does not include closed source code like Chrome allowing the community to review it. This, along with the fact that Chromium is less complex since it does not include some goodies like flash and pdf reader, makes it, at least theoretically, more secure.
For the interested reader, there is also an official blog post about the relationship between Google Chrome, Chromium, and Google.
I don't know why people are posting the uninformed answers. Chrome beta, canary, and dev are the 'bleeding edge' versions of chrome. At the end of the process, i.e. after a chrome stable build is released, you get a chromium build.
If chromium builds were the latest and greatest, google chrome would be the slowest browser around. Competitors would be leeching everything chrome constitutes of.
Furthermore, with chromium, individuals will be missing new plugins, such as Google Cloud Print, Chrome PDF reader, etc.
Personally, I stick to Chrome, I tried chromium but uninstalled within the day.
What I care more is the EULA and privacy issues related to the two browsers. Read this article which touches (a bit) of the issues:

So I have changed from G-Chrome to Firefox and back to Chromium.
