if by well you mean top-end, then it would be cuben fiber (DCF) tents as that's the highest performance fabric available these days
locus gear in japan are wizards with it, otherwise it's US companies; tarptent, HMG, SMD, and a couple of others
there is trekkertent in the UK but they never have a solid run of good reviews
We were pretty pleased with our trekkertent drift, once it actually arrived. The lead times weren't/aren't accurate at all, and the communication was fairly sporadic and crap though.
I hate this kind of thing but it seems to impact all smaller producers. Answering emails likely wasn't what they had in mind when they started sewing tents together, welding bike frames, stitching bags, etc.
