They should be equally stable --all else being equal-- since they both run in 64bit CPUs with 64 bit registers. That is to say the 32bit code runs in the same space as the 64bit... it's not like the CPU has 2 different modes or that it's got some kind of switch inside... It's all running in the exact same hardware. 32bit software just doesn't use 64bit instructions. If there is a difference in stability it's going to be in software and most likely in the drivers.
Still this is always an interesting debate.... I do hop you don't mind me jumping in with my opinion.
