The index finger tracking is nowhere near good enough to add to the immersion (or gameplay for that matter) in anything. The index is fairly comfortable, but it's also pretty heavy at least compared to the original rift cv1. I have heard that the Rift S has shit audio, so you'll want to factor in having to wear headphones/earbuds.

If you need it soon, the index is sold out for at least another few months so Rift S is still the most immediate option.
