Not sure I'm added anything to what's been said so far, but I have the 18.5 and love it. Granted the 14 wasn't an option when I bought mine, but I suspect that all things being equal I would have gotten the 18 anyway.
I say that because when I bought it I already knew that the WSM wasn't a "let me see if I like it" purchase but a "I haven't used it yet, but I know I'll love it" kind a thing. And while my regular cooks are for 2 adults, when my out of town family visits they tend to do so all at once. Plus since the 18.5" has been the work horse of the WSM fleet for so long, I knew it should be able to handle whatever I can throw at it. And if I need extra capacity I've got an 18" OTS and a 22" OTG to augment my capacity.
At the end of the day whatever your choice is, you should be happy with your WSM.
