The choice of RAID is largely personal, and based on more factors than you've mentioned here, so it's hard to be precise.
RAID 0+1 will generally give you better performance than RAID 5, especially in writes, so if capacity isn't your issue then that would be a good choice.
For most applications the performance difference between RAID 1+0 and 0+1 isn't that great. For home directories you're still likely ro be throttled by your network bandwidth more than your disk bandwidth so it's not worth worrying about.
