I would go with 3 RAID 1's given the choice.
Not necessarily for performance though.
This would allow you to have 3 control files on separate drives.
It would also allow soft mirroring of the redo logs.
And before someone jumps in with "But you don't need
to mirror them on RAID 1", I *like* having them in 2 locations. :)
As for performance, it is nice to separate the redo as much as possible.
