The last few days I've been trying out Kubuntu and Fedora Core, whereas my distribution of choice has been SuSE since version 6 or so. I thought I'd comment on the experience. Incidentally, this is not a review, it's just some uneducated comments about installing and setting up those distributions. So no posting this on Slashdot and then flaming me, ok?
Kubuntu
First impressions: Text mode installation - does the job, but looks pretty ugly: bad. Didn't ask me which packages I wanted to install - just went ahead and put a default set on: not sure if that's good or bad. Detected my dell laptop display without asking me any questions: good. KDE's defaults didn't look very nice: indifferent - I've never found a distribution which makes KDE look nice yet. Had a nice KDE network control panel: good. Couldn't work out how to make my wireless card work: bad. Didn't give me a root password, and I had to use another computer to google for the answer: bad. The fonts looked ugly - it wasn't using the freetype bytecode interpreter: bad. Plugged in my memory stick and it appeared on the desktop with a sensible name: good (SuSE doesn't put it on the screen, and calls it something like usb-p0-0023932746593249). Couldn't find many nice GUI tools to set things up with: bad.
Fedora Core
Nicest installer I've seen: very good. Nice boot screen: good, but not as good as SuSE - you still get a lot of text before it goes graphical. Needed me to select the laptop display: indifferent - until Kubuntu I wouldn't have expected any different. Default setup of KDE actually looks reasonably nice, although I still needed to fiddle with a lot of settings to make it look really nice: ok. Fonts look as good as SuSE: good. Uses RPMs: good (since that's what I'm used to). Uses firefox and evolution instead of konqueror and kontact by default: bad.
Overall FC4 just feels like a much more professionally put together system than Kubuntu. Which means the choice is between FC4 and SuSE. I think SuSE probably does things slightly better than Fedora, but Fedora has to advantage of being a bit more open, so there's perhaps a chance I could contribute to making it better.
So, I'm currently posting this while using FC4, although I'll probably put my SuSE hard drive back in before too long, since all my work is on it. But it is very tempting to change to FC4, as it's a lot better than I was expecting. The only thing I'm not sure about yet is how well supported KDE is on it. I liked having KDE in /opt/kde3 on SuSE, but on FC4 it's all mixed in with everything else. Which is probably more correct, but it complicates things a bit.
And I noticed that I'm listed down the side of planetkde now. So hi to everyone reading the planet!
