What's the difference between Ubuntu and backtrack? Like I know it's different Kernels. Is it just a deb system with all installed in it for convenience?

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form.

I think I can give only a brief idea as detailed comparison will be beyond a Q&A website.
Backtrack is customised Debian/Ubuntu style linux
As per the website of Backtrack linux it is a Penetration Testing and Security Auditing Linux Distribution, thus a specialised Linux distribution which is very good for some specific purposes.
Website further states "BackTrack is a Linux-based penetration testing arsenal that aids security professionals in the ability to perform assessments in a purely native environment dedicated to hacking.". For more details see http://www.backtrack-linux.org/
Now Ubuntu is a general purpose operating system for day to day tasks for common man. It can be used for advanced purposes. But to use it as a 'Penetration Testing and Security Auditing Linux Distribution' you would need to customise it and install specific packages. And backtrack just did that. For more details see http://www.ubuntu.com/
So you would choose a distribution based on your needs. Any specific comparison questions, I would suggest raising more specific questions.
Hope this explains little bit.
