winuae 64 bit - advantages/disadvantages?

may be a silly question: what is the difference between winuae 32bit and 64bit?
what are the advantages of 64bit version of winuae? are there any disadvantages?
so, which version of winuae should i use/prefer? 32bit or 64bit? i ask this, because:
from microsoft office 2010 i know a number of disadvantages regarding office 64bit.
so in case of office it is wise to stick with 32bit version, even on 64bit system.

There is no real disadvantages. Office is only recommended being 32-bit because many plugins only exists in 32-bit format (and it isn't really problem anymore). WinUAE does not have that problem.

64-bit allows 2G of JIT direct capable address space. (~1G if 32-bit under 64-bit Windows) and total ~3.5G of RAM. Not very useful but if you like big (or negative free memory...) numbers.

64-bit may also be slightly faster.

Last time I checked the QEMU PPC plugin was much faster on 64-bit UAE.

Probably because QEMU uses 64-bit variables heavily.
