I'll second Stainless' vote on the Presonus. It just sounds cleaner compared to some others in that range, (my opinion). But to be fair, I've never had any experience with the m-audio interface.
The Behringer stuff is pretty much a roll of the dice. Some stuff is great, some just sucks.(thank God the local shop and Guitar Center have fairly lenient return policies)
I had a C-3, got it because of the switchable patterns, it ended up being very noisy, couldn't stand it. Returned it and bumped up to a B-1 for just a little more and never looked back.
The keyboard & pad controller...guess it depends on what your recording. Mainly, do you NEED a 61 key, or would a 49 key be able to do the same thing?
Personally, I'd forget the 61 key and the nanoPad and bump up to the Axiom 49. Which will do just about what both of the other units will do combined.
But like I said, it depends on what/how you record, and for you, what's available to you.
Oh ya, Welcome to the forum.
