Since the blind levels are very high, and you state your 'M' is low, you don't just push here, you shove (all in) here with either hand, and several more down the line as well!
But you asked for a comfort level decision here, and I'll take the AK. WHY? glad you asked! With AK, I know I have to hit, and am prepared for not hitting. With JJ I have to pray any caller doesn't hit, and am still maintaining a glimmer of hope. But since there is no right way to play JJ I know that hope is likely to get crushed.
