I totally agree with connectors being through hole. there is no
comparison. Put pads/solder on both sides for additional strength.
I mix smt on bottom and top. It saves vias some times. also, bottom
side for bypass caps is totally natural - especially for a number of
the larger TH PICs that have power and ground on adjacent pins.
