Short answer: Two Pragmatic Play slots with 'Bonanza' in the name and nothing else in common. Big Bass Bonanza is a ten-line cash collect slot; Sweet Bonanza is a tumbling grid with multiplier bombs.

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.
Sweet Bonanza
The tumble works as on other grid slots. What sets it apart is the free spins: rainbow bombs worth 2x to 100x stay on screen until the tumbles finish, then their values are added together and applied to the total win.
What really separates them
The shared word is marketing. Big Bass is the more traditional game and the cheaper one to play by a small margin. Sweet Bonanza is far more volatile, with a maximum win ten times higher. A bonus spins offer on one tells you nothing about the other.
