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

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.
