For family outings this is probably the sharpest distinction between the two. The Lund 186 Fisherman GL 2008 is rated for 5 passengers, while the Lund 1625 Rebel Tiller 2012 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lund 186 Fisherman GL 2008 could be the deciding factor.
Bottom line: Choose the Lund 186 Fisherman GL 2008 if your priority is putting more people on the water - it handles 5 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Lund 1625 Rebel Tiller 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
