I went around this battery longevity mulberry bush a few times. I ended up believing that both batteries will last way longer than I or even the next owner will need them too, even if not treated most carefully.
I went with the LR because I felt happier driving it. My purchase is an indulgence rather than a necessity, so I'm ok with the $10k premium ($14k given the SR qualifies for a WA rebate).
The NMC battery suits my needs better: I'll charge at home (hopefully mostly with excess solar) and, working from home, I can dribble kw between trips each day, keeping a tight SOC band - so LFP's need to charge to 100% weekly would be a hassle for me.
Good when heart and head settle on the same decision ... wallet misses out, though.
