I vote pushers. They are set in their ways and like to win points more then use good technique. So they will be resistant to change - even if they SAY they want too.
If you are a pusher and want to become a guy with 'good strokes' you are going to have to quit match play for a while and use ball machines and practice sessions until the good strokes become the new goto pattern.
A basher OTOH is not so sensitive to winning and will readily adapt his or her technique - as long as they can still swing hard. And with good technique you can rip the ball and keep it in..
Pushers might reveal how bad their opponents are but its just a dead end technique wise. Come back and play a pusher 5 years later and they are exactly the same guy. The young kid basher - if he still plays will likely be damn good.
