 Well, hard to tell probably: 3.4 used to be fairly stable, 4.0 -- less 
so, 4.1 -- I am happy with it, but your mileage may vary, 4.2 -- I have 
not tried.  Others may have differing opinions.

 For binutils your best choice is probably sticking with the most recent 
release.  As of this writing it is 2.18.

 Well, it is a choice from two and you can have only one default.  You 
would usually want to have the default set to the endianness you most 
frequently use, so that you do not have to specify the switch; obviously 
the same applies to a native MIPS/Linux toolchain.  Besides, historically 
there used to be some bugs in the compiler's specs that made the selection 
of the non-default endianness problematic at times.  They should have been 
fixed by now though.
