I'd definitely go for the 3Ware because it has better driver support.
The driver is developed by 3Ware directly and supports all the features
(there's even monitoring software)  while Promise has a rather bad
history when it comes to Linux drivers.

The 64bit cards essentially have a longer connector which can cause
hardware problems if you don't have a slot that has some unobstructed
space where those pins would go. The 3Ware cards should - judging from
the vendor information - work in 32bit slots, but I guess there can be
the odd problem with some firmware revisions.

Humor noted, but that sig is a wee bit long... Also:
 - (La)TeX doesn't come with a "humor" environment
 - you should consider using an {itemize}
