Assuming all pots are heads-up? If i had to pick one to do forever, it would be A. Option B just seems to easy to exploit if your opp is paying attention (since you'll be donk-leading a lot of flops if u are doing so with any pair or draw). I know it will be hard for opp to put you on a hand, but it will also be hard for you to call a raise most of the time.

Both have there merits tho, in fact i've been experimenting recently with a combination of the two. 3-betting PF then donk-betting the flop. It's amazing how often ppl will fold to that shit
