The 22-2 flatback is a classic - especially if you can find one with the dive platform on the side. You can't go wrong with one of these, but they are getting scarce.
The 19-6 is a more modern design and has advantages of a 12 degree deadrise, but gives up 2" of draft. Better ride in chop and maybe a more modern console.
You could also consider a late 70s or 80s 22-2 with a 12 degree deadrise (also called an Osprey after 1980). It has about the same draft as the 19-6, but in a bigger size and more space. Better ride than the 19-6 and built like a tank.
