Note that a hotswap bay need not be capable of SAF-TE.

I have no idea about how good the newest 3Ware controllers are.

I wouldn't touch an Adaptec RAID card with half-assed specs like this.  Note
that I personally don't trust anything Adaptec at all, other than simple
onboard SCSI HBAs (and I have seen even those screw up, and it was an U320
one, at that, which ain't commodity hardware).

And a much better choice, probably.  But I never used that particular model.
Look at LSIlogic RAID stuff too, it should be as good as Intel's (the
difference being the firmware -- chose the one with the firmware you like

Whether it is better or worse than 3ware, I really have no idea whatsoever.
