hard to just recommend a random character, but assuming you're new to the game (may have missed if you already said you played it, if so my bad), some of the simpler heroes (imo) would be Punisher, Jeff, and Dr Strange.
Best to try a little of everyone until someone clicks though.
That depends on so many factors!
Like, who's currently meta?
What's your play style usually like in games?
What are your teammates playing as and what role is needed for the team?

DPS: Hawkeye is ez mode, squirlgirl is a lotta fun
Support: rocket is real fun
Winter Soldier is fun if you like picking and choosing your fights
Adam Warlock is probably The Support of all time
Loki is silly
Magik and Iron Fist if you like getting in people's faces
If you can handle his cheesy one liners though...
