I’ve just installed Opera Neon out of curiosity. It does look rather weird, and I’m not sure whether I’ll find it useful. But it’s a completely different presentation method, so I’ll try to give it a go if I remember… I do like the standard Opera, even though it’s not my main browser but gave up using it much when it seemed to be getting rather OTT.
I’ve really been rather promiscuous as far as browsers are concerned; finding a favourite and then discarding it for slowness or bloatedeness. Chrome was a long-time favourite, but I switched from that to Vivaldi, and have been pretty satisfied with it. But I still have Chrome… and Opera… and Firefox… and IE11… and Edge… and still use (or have to use) all for different reasons. I suppose the obvious omission is Safari, but I never got on with that, and, post-iPhone, post-iTunes, I am quite content to steer well clear of “the Apple experience”!
