I put the Sensah SRX Pro 1x11 on my gravel build. It's not bad, and hasn't given me any trouble.
That said, I'm keeping my eyes open for a way to go Shimano 2x9 or so. I didn't feel like that stuff was worth the new prices, and still don't. If I can get a deal on a gently used set, I'll probably rebuild.
1x11 to me is silly, too much chain deflection on the extremes. Plus I like heading uphill on a big front ring and easily dropping to the smaller one if I weak out.
