Easel vs UGS (Easel non-support of Arcs)

I have noticed the faceted bends with my machine. At the moment I’m using Easel to send the g-code, but Fusion 360 and Aspire to generate. I’m curious if switching to UGS would improve this. I’ve never had Easel complain about G2 and G3, so I’m confused. I had been intending to switch to UGS for some time, just never got around to it.
