Short answer: yes, a lot.
Long: i've used nearly all existing browsers: chrome, firefox, edge, safari etc. This one is overtaking them all. First of all, awesome UI, that you'll never find anywhere else. Second, quite a lot features comparatively to other browsers. Even to standard opera version, GX have some useful things like resource monitor.
The one and only problem: GX really needs lots of your RAM. But not much more than chrome. For me, it takes 1-2 gb at max.
Try it and for sure you'll be quite satisfied.
