low M, 88 in the sb vs early position raise

[Yossarian147]

PS Hundred Grand. I've been at this table a while. I've shown down pretty solid hands, M at 5.2. Villain (28.1/21.9/0 over 32 hands) is one of the chip leaders. He's raised the last 3 hands in a row, showing AK, JJ. I put him on A5s+, A8+, 55+, and big kings and queens. Looking at this after the fact though I think this range is too tight given his stats.

Options are to push or stop n go. Stoving it with 88 vs his 22% raising range gives me 52% equity. So I don't mind getting it in preflop given my chip situation but what factors would make the stop n go the better play?
