Only the largest Q (3xx and 3xxx series) has something resembling 2-zone cooking. And even then, it's weird, with the zones not being left/right or front/back but inside/outside. But I don't know of any Q lover that's bothered by that. I sold mine, but mostly because I'm not a gas user.
But like you, there's this non-enthusiast who shares the house. She hasn't asked for one, and would never step out into the cold to cook, but I now have a Genesis like in your picture waiting restoration and a blue one with plastic tables and side burner too.
At retail prices, I'm probably the only person here that would spend $400 on a 2-burner Spirit instead of on a Q3200. The zone issue is that important to me.
The largest Q models are only "portable" if you unbolt them from the table, which makes the Q1xx(x) and Q2xx(x) models incomparable to any Spirit or Genesis, which are never portable by any sane measure.
The Q, even the 2-burner models, will alway have fewer parts to go bad and fewer things to rust than the standard Webers.
