Should I Switch My Custom FPV Kwad to an ACK75 Frame?

Hey ppls, so i was thinking if i should transfer my custom fpv kwad to this ACK75 frame because my old frame is made for holding 2s and the props kept on hitting the prop guards so i had to trim it, plus i can take of the guard and it will become an open-pusher 75mm? My build was originally a Matrix V2 Aio fc, 4 Happymodel se0802 19000kv motors, C03 camera, GF 1614 props with Happymodel Mobula 7 v3 frame but one of the motor cables came loose from the motor( if you know happymodel motors, is not like betafpv ones, it doesn't have a board and it is just direct solder from copper wire to motor wire) so i soldered on the old motor wires from the happymodel ones on to my Betafpv 0802se 23000kv motor and some how, it acted like the old 19000kv motor? It flies normally too! Before that, in the motors tab i set the throttle limit to 85%. Should i do the transfer to this ACK75 frame? Btw is pusher better for freestyle? I dont see much ppl use pusher for freestyle, so is it bad? Is mostly for cinematic right?
