Yes. It's a different animal, so to speak. The thing with kettles (unlike the WSM) is that you will want to be able to set your kettle up easily for the type of cook you'll be doing - direct at one heat, two (or three) heat zones, indirect, direct/indirect, etc. The added space makes, imo, a huge difference. I often cook just for two - but really need the additional space because of the ease of cooking configuration set-ups. 18s - unless you are just cooking direct or doing a simple half-coal-grate-covered thing are quite limiting. Harder to indirectly roast a turkey or a couple chickens, for example, with an 18. Not so with a 22. Just my two cents.
