if we know he's really wide then he's just gonna be a pain in the arse until we play back vs him. Generally it's safer to play back at him earlier than it is later, since we send him a message early to not mess with us. This is a decently profitable situation a lot of players just pass up, simply because it's a bad looking hand and don't understand what is going on here. He's going to be forced to fold to our 3bet a huge amount of the time because (assuming things here) we havent played back much vs him before. He has a wide raising range and that means a big folding range, and also, he's a supernova likely reg, meaning he wont really flat call us at all really, generally they will just 4bet shove or fold with that stack(however may have a flatting range to induce or have a strong hand he wants to avoid overcards with like TT or something.
so if i haven't 3bet him before this is a great time to make the 3bet. Calling is also fine if you have the intention of C/R a lot of flops, but generally you want to do it with hands that can connect with flops and that have value postflop, which J6o really doesn't have too much.
Against a wide opener, having a polarized 3betting range is best, so we 3bet some junk type hands like the J6 and we also 3bet the top of our range, and we flat with alot of stuff that has a lot of value postflop like QJs and such, as it dominates alot of his opening range and we can trap him in postflop situations.
