If you don't care about code size (because you have tons of RAM anyway) is
it better to use Fastest or Fastest, Smallest?  Which produces faster code?


Either.  Both.  These days, code speed isn't simply a matter of loop
unrolling and inlining.  A program that loops and branches like crazy
but fits entirely within the CPU's L1 cache might be much faster than
a loop-free, fully-inlined version.  Profile your program both ways,
and pick the one that works best.
