Which type of chair would you recommend?

I'd recommend you go and try out chairs if possible in store. We as humans aren't all built the same size or shape so recommending one or other option is moot. I have wide shoulders so find car bucket seat style gaming chairs uncomfortable for any period of time. All the adjustable lumbar support and head cushions cannot account for that. You also have to consider the material of the chair because come the hotter months, if you don't have aircon the leather and fabric seat and back chairs get exceedingly hot. Fabric is a tad more breathable but mesh is better still.

Yeah, this is pretty much the best advice you can get. Chairs are like shoes, so you can't just fit into something because it's "your size".

Chair ergonomics come into play, sure, but only if they fit your body shape and spine curvature.

Other than your body type, it's also down to preference as AntiKytherA  says, materials matters, but also the arm rest, extended backrest, wheels etc.

It's best to try the chair before deciding on it, plus, it also depends on your budget.
