I had the Strata Premier for a year to earn the SUB, then downgraded to Strata no-fee, which has the unique 3x category for barbers/hair salons. In order to make the Premier a 'keeper' card, you'd need to at least use the $100/year on Citi's travel portal, which can be a bit tedious.
I opened the the Strata Elite earlier this year, and have already used its various credits ($100 credit on Blacklane was actually pretty good in NYC; $200 Splurge for AA gift cards is a quick 'win,' too, and the $300 hotel credits, again, a little tedious, but, it works; I prefer the Amex Platinum $300 FHR 1 night credit, personally). And I've been using the Citi Nights 6x for drinks/dinners on Fridays and Saturdays (after all my Resy stuff from Amex got used up). So, I'm actually warming up to keeping the Strata Elite, honestly.
