Both the PlayCraft FX4 FishDeck Series 2010 and the PlayCraft Power Deck Xtreme 260 SXi 2008 are planing designs, both built in fibreglass, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
The power gap is worth calling out. Rated to 425 hp, the PlayCraft Power Deck Xtreme 260 SXi 2008 has a 200-hp advantage over the PlayCraft FX4 FishDeck Series 2010's 225-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the PlayCraft Power Deck Xtreme 260 SXi 2008 carries 85 gallons versus 70 gallons in the PlayCraft FX4 FishDeck Series 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The PlayCraft Power Deck Xtreme 260 SXi 2008 is rated for 12 passengers, while the PlayCraft FX4 FishDeck Series 2010 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the PlayCraft Power Deck Xtreme 260 SXi 2008 could be the deciding factor.
Bottom line: Choose the PlayCraft Power Deck Xtreme 260 SXi 2008 if your priority is putting more people on the water - it handles 12 passengers and at 26,0 ft it has the deck room to back that rating up comfortably. The PlayCraft FX4 FishDeck Series 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.
