My brother has a Zen and is very happy with it. Basic player, but works well and has a great screen for videos.
I agree, I personally have a Blackjack II, and it sucks for watching any kind of video. It just can't handle the load on the small cpu. But it works well for everything else.
I've felt that my zen sleek was sort of lacking, but it's really old so the black and white display is understandable. Also I found that the headphones it came with sucked big time. But hey, they were free. Anyway, it was a good player, but I am now happy with my Zune 80.
I have a iPod 80 GB Classic, and I understand how everybody is like "Oh my iPod Touch is iCooler than yours." Yeah? Well iDon'tGiveaCrap. I don't really like it either, it dissapointed me, and I haven't used it in ages. Headphones break easily too.
I wouldn't go that far, I have used Creative sound cards for a long time, and have had a few problems with them.
