They are a re-branded continuation. They were re-branded because retailers apparently understood the Avengers brand more than the generic 'Marvel Universe' one. So they re-branded Marvel Universe as 'Marvel Infinite' - which has nothing to do with the Avengers, and completely failed to get them on the shelves any better than they did with MU - proving what they said was a complete lie. Then along the way they; took more stuff out the packages, made the packaging generic and cheap looking, cheapened the plastic, lessened the articulation, and constantly hiked the price (I believe the latest was something like 30%). They want to kill the line or the scale - one of the two.

Ironically, it just keeps selling regardless.

So, as MU / Infinite are the same, you can't start from Infinite and hope to see the same characters we've had with MU. Don't try collecting everything unless you have a *lot* of disposable cash. Start with buying characters you like and work up from there, but to start a line 6 years in and try and complete it would cost a lot of cash indeed. Good luck!
