5/10 on-line, jam flop or enlist preflop raiser?

[leo doc]

My first post here, so please excuse any errors/rookie mistakes I might make:

About 1/2 way into my second orbit (don't have a read on anyone), 3 mp limpers and hero limps with 4s4c in HJ, button insta-raises, sb folds, bb and all call.

flop: QsJs4h
all check to hero who donks, button insta-raises again; bb folds, others call two

Hero jams pot now or leads turn on blank?
