I agree with Gary. Each type has its pros and cons, so rather than trying to figure out which one is "better", figure out which one suits your driving requirements.
I like my LFP for a number of reasons, but some of these are probably entirely theoretical. It's less likely to catch fire - but how often do NMC batteries catch fire? Damn seldom. Mine doesn't have the evil cobalt, but cobalt-including batteries are being made and the ethics of their manufacture are being cleaned up, and really, it's not going to make any tangible difference to anybody's life if you buy one now. LFP has a longer life-span than NMC, but see above. If the NMC battery is going to last as long as your car does, how much does this matter?
The day-to-day thing that I like is being able to charge to 100% and balance every time I charge, without worrying about how long I'm going to leave it or how many times I've done that. But I strongly suspect that if I had the LR battery I'd be getting on just fine treating 80% as "full", not least because 80% of the LR is a similar range to 100% of the SR. And really, taking it up to 100% the day before I plan to drive at least 50 miles, once a month, probably wouldn't be any great chore.
I do know that when I've gone on longer trips, just twice in six months, the LR battery would have made a significant difference. I knew that when I bought the car, and the salesman tried to sell me on the LR. I said, £2,500 on the price isn't worth it to me for the few times I might want that range (and charging speed). And I stand by that. But (literally) your mileage may differ on that one. I had a scheduled 2 hours of charging stops with 7 hours driving time on a trip to Brighton. With the LR it would probably have only been an hour. But I'm retired, and taking my time on that journey is a pleasant novelty.
If I'd been concerned about charging time on long journeys I'd have paid that £2,500, and not worried about it. I suggest you work out your requirements in the same way.
