Note:

Before posting this, I looked at a similar thread, but could not find what I was looking for.

I am using Ubuntu at present. Learnt about kubuntu & xubuntu recently. Visited its websites to find out details.
Learnt that these are based on ubuntu.
KUbuntu uses KDE graphical environment.
XUbuntu uses XFCE graphical environment.

My need:

Programming for database oriented business apps using MySQL & Python. Use online stock-trading terminal based on Java.

Should I go for Ubuntu or XUbuntu or Kubuntu?
(I read that Xubuntu is faster than Kubuntu).

I am going to format my laptop. Before that, I want to download a latest copy of a good open source OS.

Can anyone please share on the following points:

1. Whether the default Xubuntu / Kubuntu installation is packed with open source software packages such as MySQL, Python, etc. or I need to download those separately?




2. Compared to Ubuntu, whether Xubuntu / Kubuntu have the 'software centre' which can take care of new / old installation of packages.




3. No setting-up of wireless internet was required in my existing Ubuntu. It was automatically detected & taken care of by the OS. What about Xubuntu / KUbuntu?




4. Performance point of view, how do they compare? e.g. My Ubuntu OS starts within 10 sec & shuts down in 3 secs




5. Any other plus or minus points of Xubuntu/Kubuntu over Ubuntu.

Thanks in advance,

Vineet
