There are some games that prefer Nvidia over AMD, but that holds true in pancake too; VR performance is mostly the same story.
AMD's mid-range cards come with more VRAM than their Nvidia counterparts, which may not gain you any more frames out of the box, but not having to worry about running out and being downgraded to a slideshow is great.
tl;dr look at pancake benchmarks and get the highest performing 10-12gb+ VRAM card you can for the least amount of money.
