Size is the most obvious dividing line here.

That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.
The power gap is worth calling out. Rated to 75 hp, the Leisure Pontoons 1823 Fish 2005 has a 73-hp advantage over the Leisure Pontoons 2123 Fish 2005's 2-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
Both are inflatable designs, which means they pack down for compact storage, can be carried in a bag, and are dramatically lighter than equivalent rigid hulls. The trade-off is setup time and the need to monitor tube pressure regularly.
