Yes, provided you don’t clog up your entire network with too much polling. Which was more common about two years ago than now, I think most people have learned that lesson. 
As far as switches other than GE, there are several popular choices. Among the less expensive ones, the Linear/GoControl are a standard shallow rocker switch, use virtual three ways (no traveler wires), and are widely available including at some big box stores.
The new homeseer switches have a functionality that so far the other switches don’t offer, and that they can distinguish between single tap, double tap, and triple tap, at both the top and the bottom of the switch, so they’re nice for zone lighting where you want to have the whole room come on with the single tap, but you might want to have different sets of lamps come on for the double tap and triple tap. Or even use those tap patterns for something completely different. And because their new, they are also Z wave plus, which is nice. That gives you longer range and better pairing in, both valuable for switches. However, they are reportedly a little slower then switches that only do single taps, probably because they’re waiting to see if there will be a second tap.
Among the more expensive switches, both Leviton and Cooper are good. Leviton has an unusual form factor in that you only tap the bottom of the rocker, never the top. Cooper has some decorator options which give you different color combinations and some different shapes. Both Cooper and Leviton are also very well engineered switches. Both have Z wave plus models coming out in early to mid 2017, but right now you can only get the Z wave classic versions.
Zooz are brand-new wall switches in the budget category, but so far community reviews have been mixed.
Dragontech is a Z wave plus brand that’s gotten good reviews for the plug-in pocket sockets, but not for the wall switches.
There are a few other fairly popular brands, including evolve and enerwave, so just depends on the exact features that you’re looking for. It’s good to shop around, because prices will vary a lot and Amazon isn’t always the least expensive.
