I tried SUSE maybe 2-3 years later than you (around 2003). The first thing I disliked was: they have yast on top of standard configurations. First of all, it is quite unpleasant to deal with: infinitely long single file containing all configs. Next, you change one single thing, and yast to enable your change touches all config files. Some time after you made some change you discover something (unrelated) doesn’t work anymore, and you can not use timestamps to investigate when bad change happened and how. I was joking about SUSE with my German friends: how come German tool is named as abbreviation of English (yet another system tool), not German?

But what really did it for me was: stock installation from SUSE DVD (that specific release) was easily crashed by program with memory leak run by regular user. I replace SUS stock kernel with downloaded and compiled with all default option kernel from kernel.org, and it happily kills memory leaking program (even the one run by root). Not kernel shipped with SUSE. This: memory leak, out of memory condition is one of the tests I usually do when I’m testing [quite] new for me system (and some other stuff).

I turned away from SUSE then, and never looked back.

Just my $0.02
