which engines are strong 64bit or 32 bit ?

The question is wrong.

An engine compiled for 32 bits and 64 bits uses the same techniques, algorithms, ideas, etc. But the 64 bit engine takes advantage of the resources put at its disposition by the 64 bits hardware. So, the same 64 bit engine reaches bigger depths than a 32 bit engine and hence performs better.

So yes, a 64 bit gets better results than the same engine at 32 bits, but not because is stronger by itself, but because the "hardware" made it stronger.

Hope this is not confusing.
