Short answer: Both are cash collect slots with a fisherman. Big Bass Bonanza has the higher default RTP and a multiplier ladder; Fishin' Frenzy has the higher maximum win.

The mechanics
Big Bass Bonanza
The fish symbols carry money values. In the base game those values sit idle. During free spins a fisherman wild gathers all of them at once, and every fourth fisherman adds ten spins and raises a multiplier on the fish, to 2x, 3x and finally 10x.
Fishin' Frenzy
The same collect idea later used by Big Bass Bonanza, in a plainer form. There is no ladder and no multiplier; the round's value comes from how many fishermen appear and what the fish are carrying. Two fishermen on one spin collect twice.
What really separates them
They are the same mechanic at two stages of its life. Fishin' Frenzy set the pattern: fish with values, a fisherman who collects. Big Bass Bonanza added progression, so a round can grow from ten spins into thirty with fish values multiplied. The price of that ladder is a ceiling less than half as high.
