A few random thoughts, mostly on Mac versus other sailboats ...
UNDER SAIL: If you care to do it, either boat will sail under one rag. The X might be better under foresail, the M under mainsail alone. Whatever ... performance under one sail isn't stellar, so I might prefer motoring that day.
MOTORSAILER: A big outboard is
the defining feature of these boats. Agreeing that the Potters are great boats ... you'll never get home in a hurry. That means on the water adventures can't cover as much distance. On SF Bay the 50hp will permit a weekend visit to any destination you choose. You can sail over (Sausalito, Angel Is, Tiburon, Pier 39, pick any), then motor home. If the wind is cantankerous, motor over, then sail home. That's not feasible in a conventional sailboat.
NOVICE SAILING: It also helps define the boat for a novice ... if winds are suddenly gusting over 25 mph, I can drop the sails and safely motor home through a nasty chop. In a conventional sailboat you can motor home slowly, but in nasty conditions you might need the sails up for stability ... to a novice sailor, that's spelled C.O.N.U.N.D.R.U.M !
TRAILER-SAILING: Is a smaller trailerable quicker to launch & recover? ... I doubt it. Once you understand the process you can reduce the time to less than 2 hours, in-and-out. (Study Jeff Stagg's video and you'll be in-and-out, complete in 30 mins per day

) The Mac's rigging is as basic as any, so the time is spent to park the tow rig, retrieve the tow rig, wash-down the boat, wash down trailer & brakes, flush the outboard, etc. The majority of that time applies to every trailerable, not just the Mac.
FISHING: With a $35 mod, the X's backstay becomes adjustable and optional ... use it or not. It's not holding the mast up. It's just a nice-to-have, enhanced sail control. If you're fishing, and not sailing, just clip the backstay to any handy lifeline or shroud that's clear of your casting arc.
As stated earlier, whatever your choice just DO IT, get onto the water. Your life will improve!
