I’ve been using iPhone X s max since December and I would say this phone will give you luxuries feel than iPhone 11 because that phone has myriad issues which I heard from iPhone 11 users. further more their is no much difference between iPhone 11 and Xs max. iPhone 11 has just A13 that’s it. it doesn’t make much difference so its better to go for iPhone XS Max over iPhone 11 to save money you will not regret after purchasing.
