Do you want an outdoor griddle or a BBQ? I think how you view a BBQ is fundamental to how you fuel it.
If you want to be cooking outdoors a lot, easy and quick to heat up and less faff the answer is gas.
If you want that traditional smokey flavour and are prepared to concentrate on making the right fire and adapting your cooking accordingly then I think a charcoal BBQ (ime) gives the best smokey, man+fire outcome. BUT it’s so much easier to burn everything and leave the middle raw if you are not patient and don’t adapt how you cook.
We’ve got a B&Q kettle charcoal BBQ. I never find it inconvenient. Light it, prep everything else then cook on it.
If you go for charcoal having a good lighting routine/technique is a must.
You want to be able to get it going reliably. A lighting chimney with fire starter blocks is one way but good basic fire lighting and a stock of kindling will work well too.
Between April and September we BBQ probably one out of every two dry weeks at some point over the weekend. We do veg as well as meat on there.
If we had gas as well we would possibly cook more outdoors in the week but my experience of going to other houses for gas BBQ food is it doesn’t smoke in the same way (still make tasty food just it’s more like indoor food) so for me only one BBQ means charcoal because otherwise I can do dinner in the kitchen and walk down the garden with it.
I reckon charcoal are overall more pricey than gas from a fuel perspective.
I am probably totally biased as I was fortunate enough to be a scout and was therefore trusted to cook on wood fires and BBQ s from my early teens. If you can cook two meals a day for a week on an open fire then charcoal is a doddle.
