Thoughts on .GUIDE TLD?

I've seen a few sites ranking really well with the .guide extension. Has anyone done actual testing with some of these new extensions recently?

I stick to .com's, and haven't tested anything myself. But there are three projects I'm looking to start and there are awesome 1 word .guide domains available.

I am running a test on .best domain but its still quite early to say anything after 20 web 2.0s and some random links its on the 3rd page for most of its keywords, let see how this goes.
