I made a few 600 point teams and need some advice of which is probably the most balanced to play with and of any figures that i shouldnt have on the team and replace them to make the team stronger and more efficient.

Marvel:
(CW) Hawkeye and mockingbird 148pts
(CW) Hawkeye 98pts
(CW) Nick Fury 45pts
(CW) Sharon Carter 45pts
(CW) Tony Stark 41pts
(CW) Thor 150pts
(CW) Captain America 60pts

(CA) Captain America 89pts
(Avm 005) Hawkeye 75pts
(SI) Iron fist 70pts
(CA) Capwolf 100pts
(CA) Falcon 79pts
(CW) Lockjaw & Hairball 82pts
(CW) Tigra 57 pts
(CW) Nick Fury 45pts

(AVM) Thor 250pts
(AVM)Hawkeye 75pts
(CW) Morgan Le Fay 122pts
(CW) Sharon Carter 45pts
(CW) Nick Fury 45pts
(CW) Dinah Soar 25pts
(CW) Donald Blake 33pts

(CA) Black Panther 128pts

(AVM) Hawkeye 75pts
(SI) Iron fist 70pts
(CA) Falcon 79pts
(CA) Captain america 89pts
(CW) Donald Blake 33pts

Thank you for your help and time!!

I would go with the first one for sure. Hawkeye and mockingbird have awesome potential, and everyone else on the team is good, too.

Honestly, though, I would mix and match your team around to do something like this->

148 CW054 Hawkeye and Mockingbird
89 CA001 Captain America
33 CW010 Donald Blake
122 CW049 Morgan Le Fay
150 AVM200R Thor
41 CW011 Tony Stark
583

Instead of leaving those open points would it be better if I replace tony stark with 50 point SI spiderman?

Yes it would.
