What kv motor to match with an ezrun for a summit?

Hello, I am new to brushless setups and I am looking for some insight on my current project which is going brushless with my summit. I have 2x 2s lipos already and want to run 2x 3s as well. Since all I do is bash I assume the 150a ezrun is the cheapest and most reliable setup? what I do not know is what kv I should get. does a higher number mean more torque? Also, what motors have the best reliablilty / warranty on them? Is the ezrun 4465 a good choice to run 4s and 6s vs a medusa or neu? Im not trying to break the bank but I do want something that will last and go through some bashing without overheating. Thanks
