Over the years for USB scopes I've had a Picoscope 2000 series, a BitScope BS50 and the Analog Discovery.
The Picoscope I used about three times before it was relegated into a drawer for several years, after which I sold it. The BitScope I still have, I bought it to use on the road, but the software is awful, and I haven't used it since receiving the Analog Discovery six months or so ago, which is the only USB scope I've ever used frequently, it's feature packed and the software is slick, bug free, performant and simple to use.
It's not to do with screen real estate either, I run three 4K monitors on my bench setup, and the USB scopes remain in the drawer.
While I can see the attraction of USB scopes, far more often than not they end up gathering dust. The only way to find out is to try one, but if I were a betting man, I'd put a fiver on it being a disappointment compared to a real scope.
