Back in about 2001 I had a stick of bad Crucial, they replaced it for me before I even sent the bad one back. I'm currently using Crucial in my Powerbook G4 which is notoriously picky on what RAM it will accept. I'm also running a couple gigs of it in my main PC. I've been very satisfied with them so that was what my vote was for.
If I was allowed to vote twice, I would also toss in a vote for Mushkin, I'm using 2 512 modules of it in my A64 and it has been great. I've also got a couple gigs of it in my slower C2D machine, again without problems.
I ran 2 gigs of Patriot in a C2D machine for a while, had to run it in compatability mode (on a cheap ASRock board) to get it to work, put it in a Gigabyte board and it ran perfect.
I guess what it boils down to is if it isn't giving you any problems there isn't any reason to dislike it. If you aren't pushing the timings and overclocking I doubt you'd see much difference between cheap RAM and expensive RAM, provided the cheap isn't defective.
