2 villians, similar postflop aggression

Hand 1:
BB is aggrofish, 64/49/31, 46% river bet, 36 FTFCB, has bluffed paired boards before, tends to overbluff in general. He shouldnt call 3b with as many 5x as he would a 2bet so I guess its a call? He can float with Ax and on a dry board with given action he could be trying to get action from a queen? Although sizing is pretty big and might be a tell.

Hand 2:
V is 47/28/6 with 50% river bet, overbluffs in many spots, FTFCB 53. Seems like he will bluff in this spot frequently but he has too many 9x right? He only have busted hearts 40 combos and easily 80+ 9x and 33, 44 sometimes.

1st call 2nd fold, i'd like better sizing on first hand but in the second to me you are calling too much if you call into that river.
