Very well, once you have the compat-32 libraries installed.

Solid and actually preferred due to additional space for stack and
heap randomization, use of the NX (no execute) bit for stack. The
code size is larger, but you get to use 8 general purpose registers,
as well as get better HW acceleration for crypto or RAID.
Not to mention the ability to use more than 2/3/4 GB in a non-hackish
way.

It depends. If the current servers are working, don't mess with them.
If you need to provision new ones, go for it.
