I've been needing a new primary keyboard for some time, but I have to admit the hobbyist rabbit-hole is absolutely repellent to me, so I'm glad to see the Logitech G Pro X is waiting for me whenever I can put up the cash. I love my G903 and this board will even share the same Lightspeed receiver.
My previous favorite (and high speed record) was the Matias Tactile Pro 3, but it's incredibly loud and I haven't used a Mac personally in many years now. It also uses an unusual narrow layout.
