wait, wats the reads and stats? button is the 3bettor and u have two different stats...anyways, id probably 4bet to $150 and call shove. Your not really too deep and if you assume that SB and MP both fold 4betting is +EV given these ranges for btn - Initial 3bet range: 99+,AJs+,KQs,T9s,98s,87s,76s,AJo+
calling 4betshove range/5bet shove range: KK+
