I don't understand the reasoning against gas bbqs. Why is gas a no-no? I use both gas and wood, each have their uses, their advantages and disadvantages.
At home I only use gas bbq for multiple reasons. First of all, although I live in the country side my house is an apartment so I would not want to disturb the nieghbours by lighting a wood or coal fired bbq on the terrace, I'd love to but I can't. Given the climate where I live the bbq is used all year round on a weekly basis if not more often so ease of use plays a big role. A gas bbq is ready to use immediately, quick to get to temperature and quick to turn off. Cleaning would become an issue if using solid fuels, you need to lei it cool down and clean the ash. With gas I can just brush off the grills when still hot and it's ready for the next day.
Taste wise I think there's a slight difference, not much compared to charcoal but more pronounced when compared to wood, I use dead carrob wood which is local to me.
Nowadays I use it for almost every type of cooking not just meats, everything goes in, vegetables, fish, pies, pizzas…
