Any of the full sized utility quads should be fine for that, especially 4x4. On a steep climb, you'll have to be careful regardless since the ATV's you're looking at aren't built for 2 up.
The 400 has more than enough power for mudding. Obviously, it won't throw mud like an 800cc V twin but it's a hell of a lot lighter and will do just fine. The older 4 and 500s used to be the monsters, they can turn mud tires.
The Can Ams are awesome ATVs. If you can afford it, go for it! They're pricey but damn nice machines.
