Rather than comment on the issues, here's a concrete suggestion of some replacement text for the page, to act as a strawman:
"The 32-bit version will run on a wider range of hardware and generally may experience fewer issues, so is a good choice if you want a system that Just Works.
The 64-bit version is only for 64-bit hardware. It may require some knowledge of the issues that can arise on such hardware. Choose it if you feel you will be able to cope but choose 32-bit if you think you may be out of your depth.
See [some suitable page] for a more detailed explanation of the difference between 32 and 64 bit software."
