Hi

I have 32 and 64bit pc's with f9, I believe 32bit is less troublesome,
Is there any big loss in speed running 32bit f9 on 64bit cpu?

There's some speed penalty. Native 64 bit application benefit from having more 64 bit registers on the CPU.

Is 32bit more stable than 64bit?

Define "stable". If "does a 64 bit kernel crash more often than a 32 bit kernel", the answer is no. 64 bit is on the parity with 32 bit when it comes to general stability.

Now, when it comes to non-free binary blob device drivers, the availability of non-free binary blobs is somewhat better for 32 bit than for 64 bit. To my knowledge, there is no 64 bit version of a browser Flash plugin.

If you do not need Flash, and you do not use non-free binary blob device drivers, 64 bit will work just as well as 32 bit.
