Kylix didn't suck per se - the CLX sucked. 2 frameworks that were almost, but not entirely, compatible was a big mistake. Borland were just too clever for their own good. They didn't understand that Linux is a moving target and not being able to keep up to date with the various libs and toolkits killed the product. Try getting Kylix 1.0 to run now... it's not a trivial task. It's painful. I could more than likely install Delphi 2.0 (first 32 bit version, though 3.0 would be "safer" as 2.0 was a bit of a mis-mash) even now on Windows (probably 1.0 on a system that still supported WOW for 16bit apps.)
