I like em all. I know I will offend some.. because that isn't anything NEW.. I don't want to sleep on a 20' boat if it was on the trailer and sitting in the yard, let alone at sea. AND The definition of "CABIN" definitely varies from one person to the next. In a 20' vessel I got to say, I like a cuddy the least of all the models.
There I said it. The cuddy is near useless TO ME due to its size. The cuddy winds up being storage for more crap that you rarely ever need on the water in the first place. By definition a Walk Around has a smaller cuddy yet so as to be even worse.
Compared to the Wellcraft, the 2200 Pursuit has a 30% larger cuddy (approx.) which still rendered it useless save for a place for little kids to play/sleep and a potty. Climbing out on the bow to retrieve the anchor is really special in anything but calm seas in a cuddy. (At least the windshield opens on the V like a bowrider and the hatch can be slid forward so you can take in the anchor without actually crawling out and standing on the deck.)
Other features of the 20' center console that I like are the better balance/performance and a lot more room for fishermen to move about and cast. I choose to have room to move about over shelter.
I don't think I could put 9 people on a Cuddy like I did last year coming off the scallop grounds. Even with the T-top we manage to cast fish 4 and 5 people in relative comfort. Something you won't be doing in the cuddy, let alone with the curtains up. So you let the curtains down and store them. Where? In the cuddy, Right? Otherwise it would be useless to need them but not have them.. Cuddy becomes a catch-all
Naturally there are always exceptions, It does depend on the boat. The 23' Whaler had a way too large center console that housed a potty. All well and good except it ate up space in the boat. I would venture to guess that the reconfigured V-20 center console in my signature has near 20 sq.ft of additional deck space over the 23' Outrage.
Step up to a 25' to 30' boat and OH YES! Hardtop Cuddy, with plenty of boat for folks to move around. Nicer cabin that you can use. Now your cooking with gas.
I simply ain't going to leave the house if I got to run a space heater..
