Dive computers have become very specialized in the past couple
of years.  Many folks used to be content with a simple "hockey
puck" style of computer, but now they're seeing air integrated,
hoseless, Nitrox, altitude-adjustable choices.
The two computers you've mentioned are both excellent.  I'm using
a US Divers Monitor II as my primary computer, but have thought
seriously about buying the Nemesis for my Nitrox diving.
--- Dive, dive, dive!
