amd64 is probably the better choice, as Greg points out.
On the good side, amd64 also has twice the registers, and can perform
64-bit math. Both usually make software run faster.
On the downside, 64-bit increases memory pressures.
Also see x32, <https://wiki.debian.org/X32Port>. It takes advantage of
amd64 benefits, and tries to reduce the memory pressures.
