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.

If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sweetwater 2423 SC 2004 could be the deciding factor.
Bottom line: Choose the Sweetwater 2423 SC 2004 if your priority is putting more people on the water — it handles 15 passengers and at 24,0 ft it has the deck room to back that rating up comfortably. The Sweetwater 180 FC Challenger 2000 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
