I guess it really depends on what your doing or want to do. I just stick to either 6.5.22 or 6.5.30 for my general purpose systems because of compatibility with modernish software/compilers.

I have an Indigo2 Extreme I use as a COFF system and its running 5.3. I find 5.3 to be very fast and much snappier than 6.5, I also have a 6.3 disk for one my of o2's - it's pretty snappy - I didn't even realize it was 6.3 at first. I honestly was impressed how snappy a low end o2 "feels" under 6.3 and I might play with that some more in the future.

One thing that stood out to me regarding 5.3 vs 6.5 was I put a SCSI2SDv6 into my Indigo2 Extreme and created a SD boot disk for both 5.3 and 6.5 - 5.3 ran absolutely fine from the SD card. 6.5 ran like crap. I sort of took that as much more going on under the hood with 6.5 and illustrated perhaps its more lightweight for running on older hardware
