Both the Xpress SF Series - X20SF 2008 and the Xpress X22 Bay 2011 are modified-V designs, both built in aluminium, 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?
On paper these two are close siblings in the size department - Xpress SF Series - X20SF 2008 at 20,0 ft versus Xpress X22 Bay 2011 at 22,3 ft. Weight tells a clearer story for trailering families: the Xpress X22 Bay 2011 tips the scales at 1 709 lbs - 211 lbs less than the Xpress SF Series - X20SF 2008 at 1 498 lbs. 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.
Both boats share a closely matched power ceiling - 200 hp for the Xpress SF Series - X20SF 2008 and 200 hp for the Xpress X22 Bay 2011. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup.
