in terms of algorithym, maya, max, xsi, LW, all use catmull clarck.
the issue is even not doing higher lever tweaks it screws up the wire. this makes it unbareable for me to model and tweak.
take a look at older version of maya subD display at the bottom of he page here.
more here too
also in most apps now, u can edit subD verts directly on the surface, not at the poly cage point. which make modeling a lot more accurate and flowing in other apps [xsi, LW, modo]
i guess its a matter of preference at the end. if u can bare modeling in maya, great. unless im getting paid or have to use maya, i really wont for modeling.. anymore :p
