I bought Nvidia again, after I sold my 3080 for 400 dollars after almost 3 years, because of features like DLDSR, DLSS, DLAA, Reflex, NvEnc/Shadowplay, RTX Remix, RTX VSR and I could go on.
...and RT does matter for me, as I will be playing Diablo 4 and RT is going to look amazing on my OLED monitor here. Dark environment + Spells = Awesome for RT. Looks unreal. Already seen it in other games.
I paid 530 dollars for my RTX 4080. How? Sold my 3080 for 400 dollars and got Diablo 4 for free, which I would have bought for 70 dollars anyway

Paid 699 for my 3080 on release, and got it the day after launch.
Tons of games can be played with RT and high fps when DLSS Quality is used. Most AMD users are in denial because RT ON equals unplayable in most cases. I played tons of games with DLSS2 and RT so far. RT is not worth it in some games, at least not on high settings, but RT can transform some games and especially older games. RTX Remix is awesome. DLDSR is awesome. Playing old games with RT mods, awesome.
Completely revamps games. Especially older ones.
You don't know, because you can't use it. That's human nature; Denying. I know how it works.
AMDs multi monitor watt usage is not fixed at all. All new custom 7900XTX suffers from it. Just read the latest 7900XTX review on TPU. Was tested recently using newest drivers. AMD >said< they would look into a fix but never fixed it. AMD loves to talk. Talk is cheap.
I buy what I want, you buy what you want. A GPU for me is peanuts, I change every 2-3 year. Could not care less about longevity. Nvidia sits at 85% marketshare for a reason. Consumers vote with their wallets. As long as AMD don't offer way superior value and can match Nvidia features just slightly, I won't be considering AMD GPU.
I have an AMD platform tho. Their CPUs are fine - GPUs, not yet for me. Most I know with AMD CPU, use Nvidia GPU
My last AMD GPU was 5700XT, a temp solution for a 2nd PC, and it had BSOD and black screen issues for months and months after release + VRM temps were insane at times. AMD fixed it in drivers, by gimping the performance slightly. Tons of users had issues with 5700XT for 6-9 months post release, simply google it. This was my most recent AMD GPU experience and it was awful.
My last great AMD GPU was 7970XT, but first after Cata 12.11 which fixed alot of issues and upped performance (took them ~9 months as well).
So yeah, AMD is better for longevity at times - depends on games played etc. However they most often have a very rough launch with new hardware and lacks proper support when you look at less popular and early access games.
AMDs software team is just smaller than Nvidias. Way smaller. This is why they can't match Nvidia features. That and lack of money. This is why game performance varies ALOT from title to title on AMD cards. Nvidia offers good performance across all games. AMD mostly offers good performance in >popular titles and benchmarks< because they know this is what reviewers will be using.
I play alot of early access games, they tend to run waaaay better on Nvidia as well. Nvidia have launch drivers ready for ALL GAMES on release day, even early access games and beta's - often several days before actual release - AMD does not.
Also the resell value of Nvidia cards is much higher. It's like selling an iPhone compared to an Android phone on the used market. Tons of buyers for the iPhone, little to none for the Android phone, which lost 80-90% of its value. This is something you forget to add in
