I think the bigger problem with WebKit-based browsers on platforms other than macOS is the frequency of updates. For example, I find GNOME Web on Linux/*BSD perfectly suited for my own web browsing, but depending on the distribution you're using updates can be fewer between than even Safari's once-per-year big updates and far more infrequent than Safari Technology Preview's or Chrome's update schedule. There aren't really any good WebKit-based options on Windows, though. IIRC Midori runs on Windows but is GTK based and feels out of place.
