Well I haven't used Max+Plus for a long time (> 4 years!) so it may be
different now. In those days they used a variant of VHDL which was not
particularly good at defining right down to the macrocell level. Lattice use
ABEL which IMO is better suited to CPLDs as it's much easier to fiddle with
the macrocells. The devices have also come on a lot since then. Can't really
give you a valid comparison I'm afraid!
