Im running a 0+1 setup on 4 WD 250 GB drives.
In both setups, (01 and 10) you will get about 2x write (same as raid 0) and about 4x read (2x raid 0).
As far as your performance is concerned, It will more likely come down to the hardware and what it supports. If your board recommends a specific setup, you'll want to use that setup.
As far as reliability is concerned, neither should really be considered superior. In both cases a drive is equally likely to fail (not from raid configuring, but from ordinary drive failure) also in both cases, after the drive fails, the rebuild process is identical. Insert new drive and tell computer to rebuild your array. It will copy the mirrored disk to the new disk.
Overall, i really dont think there is a significant difference, which is why many boards provide support for 0+1, or 1+0, but not both. (some boards will provide both). If I had the choice though, I would do 0+1 again. Ive had a drive fail and the rebuild was rather quick and painless.
