There exists a small but measurable performance hit for at least one test case (using Int as keys, obviously).  Perhaps the bias would be the other way if we were comparing EnumMap to an IntMap wrapped with to/from Enum.

Perhaps some SPECIALIZE pragmas would help here.

Actually I tried that by adding SPECIALIZE to insert, insertN and lookup.  it seemed to make the insert benchmark competitive but not lookup.
