Yes, they're all popular and well-regarded. And, even though I've used real synths for decades, I don't generally find the UI on these synths to be a nice experience. Some are better than others, but they're nearly all much harder to read than a UI that adheres to OS UI guidelines would be. Most are not scalable, and so are literally unusable for me (my eyesight isn't what it used to be, even with corrective lenses, and it's never been great), unless I change the resolution of my display. Even at 1080p many are too small on my 15" laptop, and I usually run at and prefer to run at 4k. The type used is often abysmal. Pretending to be a squinty little LCD panel, for example, when we have infinite pixels is just plain stupid. The only reason old synths had those little panels was because big panels were expensive and graphical displays (CRTs) were too big to put into a keyboard form factor. It makes no sense to use the beautiful displays we have today and use them to reproduce all the compromises of a former era, but it is almost universal. Nearly all of the most popular VSTs impose these kinds of ugly restrictions on their UI. In short: A lot of VSTs are barely legible, ugly, utterly inaccessible, and just all around stubbornly wrong on usability for the sake of looking "cool". There's nostalgia for a simpler time, which I understand, and then there's the sadistic UI abuses found in many VST plugins (and audio software in general), which I abhor. Obviously, I have strong opinions on the matter.
