So, if both graphics card are in the same price, get the RTX 2060, they're the same price anyway. If the 2060 is a bit more expensive, ask yourself whether you want ray-tracing or not.
Also note that ray-tracing in 2060 at high-ultra setting can be pretty choppy experience in some games. Ask yourself whether or not the 2060 is worth it for you. And please don't let anyone from the internet make choices for you. Take the advice, ask yourself, and decide. Because no one in the entire galaxy knows youself better than you.
I am answering in the order you have asked:
Yes the 2060 will give more fps and you can also get playable fps with RTX on.
Yes, but price to performance proposition is still there
There is a cool video made by linus about what hardware do you want for VR. i'd say go for the 2060
