I have no personal experience but I have been looking at the specs and reviews.
The first thing you notice is that there is a lot of emphasis on gaming and that most games are optimised for 4 core CPUs. HW should benefit from the Ryzen's eight cores so may be better than a gaming style review might suggest. I don't know which of the many available benchmarks would be closest to HW.
However, the clock speed of a single core on the cheapest (Ryzen 7 1700) is lower than a similarly priced Intel chip so sample set loading times may be a trade off. The Ryzen 8 1800X should be OK but is more than I would normally pay for a CPU.
Also worth noting is that the current CPUs do not support graphics so you will need a separate graphics card, which will even up the pricing slightly. Motherboards are available with graphics ports but they are made to support some AMD A-series chips that will be released in the future that do support graphics.
The only worrying thing I noticed was that the CPUs seem to have variable clock speeds depending on load. I had to switch off that feature on my Intel chip because it would not react quickly enough for music. It sounds as if that might be possible with a BIOS setting but I have not found anything definite about it. Conceivably, disabling that feature may restrict the maximum speed you can use. Alternatively, running it flat out might cause it to overheat.
I am not quite ready to upgrade yet so I think I will let someone else find out if the last point is a real issue or not.
