I bought a 2020 10th-gen i5 MBP, but I'm returning it. I have a 2018 i5 MBP, and my primary motivation to buy a new one was the keyboard. I've already had the butterfly keyboard replaced twice on my 2018.
However, I just can't bring myself to keep the 2020. The only noticeable difference is the scissor keyboard, and that's just not enough—as frustrated as I've been with butterfly one on my 2018. I've decided I'd rather send it in a third time for repair, if necessary, and wait for the 2021 MBP with (presumably) mini-LED, a 14" screen, and hopefully a better FaceTime camera.
At least Apple has been quite speedy in their repairs of the keyboard. It has only taken about 3-4 days, and I do have an iMac Pro at home that I can use—especially now that I'm quarantined and working from home—when I send the MBP in.
