Take Taiwan, the x90 Pro now is 34888 ntd. The s22plus cost 31.000 ntd with 256gb last year list price. Likely thr s23 plus will be 34.000ntd this year.
Yes you can import yourself and get a vivo x90 Pro for 25000ntd, but then you have zero warranty, many Google services not working and notifications that don't arrive plus spend hours on debloating.
Outside China the vivo is just one thing, ridiculously overpriced.
And take dxomark, the Samsung s22 ultra had 135 points vs 137 for the vivo x80 pro. The vivo was more expensive, and lost in all other categories. Dxomark doesn't compare software quality. Now clearly the X80 pro outside China was a really bad deal.
I guess the x90 Pro+ will not even top the camera ranking on dxomark, the results on full auto simply aren't consistent enough. Its the new benchmark for night time, but no more. Point and shoot the Pixel 7 pro wins. You can get better pictures with the x90 Pro+ but it takes work and luck...
Neither will Samsung. I expect both to end up around 145 points, some things the vivo excells like night mode on the zoom and ultra wide vs the competition aren't tested. Vivo right now is king of portrait and night mode. The main camera at day is a bit to unreliable vs Pixel or Mate 50 pro. Battery the x90 pro plus may win but only because of faster charging. Audio is mediocre. While my screen on time is pretty good (mainly indoors), my idle drain is crazy - it's 1.5% hour that includes airplane mode overnight. During the day it takes 2-3% per hour (albeit with 2 Sims inserted). Without vivo.pem idle drain is too high. With it you receive no notifications.
It's clear why vivo removed the screen on time from their battery stats... Likely in reviews reviewers don't notice the notifications missing and compare it with vivo.pem active. Anyhow reviewers don't move their own apps to a phone so numbers always look better.
Now if you pay Chinese prices it looks different. The s23 will be 35% more expensive. Chinese cannot use Google services anyhow so for them the equation is likely skewed towards vivo.. but yeah only if you keep your phone over 2 years. Vivo resale value is very low. And at the 3-4 year mark Samsung will continue getting updates while vivo will just receive more and more advertising that you need to remove with adb debloat...
Only if vivo upps the software game they can be a serious competitor if you don't have brand loyalties.
Actually I had hoped for much better battery life. I think pixel 7 Pro or s22 ultra snapdragon would not be much worse, because they have much better idle drain.
