I've had an 18.5" WSM since 2006 or so and a 22" for a few years. I think they are one of the best values in smokers. Capacity is greater than a BGE. Adding a controller like a Cyber Q/DigiQ makes it set and forget it easy. Adding charcoal and wood chunks is easy too. But, you usually don't have to do that as a full load of charcoal lasts 12+ hours. As far as capacity goes, you can generally fit a couple 15 lb briskets in an 18.5" WSM and bigger ones in the 22" one. The 18'5" is much more efficient. The 22" burns through charcoal at a higher rate, plus it uses more just due to its size.
I retired my 2006 WSM in 2020 when a small hole burned through the bottom and the grates needed replacing again. Still, it saw thousands of pounds of charcoal and was worth the $200 it cost way back when. You can find them used on Facebook marketplace for a pretty reasonable price. That is where I bought my 22" and 18.5" replacement.
