By nothing better I didn't mean there aren't specific boards that don't favor AKs more than JJ
I'm talking about:
How much money you'll make with the hand
How strong it is preflop
How strong it is postflop when you don't hit
How strong it is postflop when you do hit

Realize that when jacks are the overpair to the board jacks are a STRONGER hand than just top pair top kicker. 43% of the time jacks are the overpair to the flop. 10% of the time jacks hit trips.
Preflop jacks are 57% favorite if all in
Postflop jacks are ahead more often

Also, jacks are behind only vs. AA KK and QQ
AKs is actually more behind against AA

jacks get paid off in set over set situations

there are more ways in getting money with jacks than AKs
I mean, flushes are easy to read

and a QJT board doesn't look too inviting
but hitting a set on a 2JA board is a very well-concealed hand and will get paid off by a pair of aces

jacks play stronger pre-flop and have a better chance of being strong post-flop
AKs might hit some very strong hands, but those are not going to get paid off as handsomely as an overpair or a set - which are relatively weaker, but have a better chance to make money

and I mean, seriously, WHO would call on a 2345x board? They better suspect you have an ace if you raised preflop.

"- AK pairs an A or K on the flop less often then JJ is an overpair to the flop, but it is also a stronger hand."
Untrue
imagine the following board:
777Ax
anyone with an ace will split the pot because the kicker no longer matters

now imagine
777T9
jacks will win the pot from someone holding a ten or a nine precisely because it's an overpair

there is no situation where you could say that the TPTK is a stronger hand than an overpair
compare:
25T flop AT has TPTK
JJ is an overpair

there is no flop where TPTK is stronger than an overpair barring draws
