I use it. I find it reliable, and yes definitely a better alternative than DA. Good place to host your art.

I'm not planning to use it. I've invested too much time and effort into my galleries on FA and DA to just turn my back on them. And, despite the many problems with both sites, I'm not about to abandon the followers I've acquired over the years just to pursue the latest fad platform. That is, unless it has a demonstrably larger user base and/or significantly better user experience.

Years ago, I was close to moving my main gallery over to ArtSpots -- and then the site disappeared, literally overnight. I'm not eager to repeat that experience.

Well, I wasn't thinking about leaving anyplace I'm already at, I'm just looking to expand my audience a bit.

That seems reasonable. For me, it's also a matter of "yet another platform I need to maintain," and I'm already on a half-dozen or so.
