Should I use CF or SD card?

I just bought the 6-in-1 card reader for the XL. What media type do you guys favor to use, the compact flash or secure digital? Why? Or do you prefer memory stick or one of the others, and why?

SD is much cheaper than CF!

compact flash, a lot of members including myself have problems with SD. i never had trouble with compact flash

Yeah, I read through some post and saw that people were only using CF. I figured there had to be a reason. So I ordered a 1GB Sandisk CF! Thanks!

yeh go CF.... ive had a few issues using Sandisk SD's
