So practically speaking, if the time doesn't matter (have something else to drive around no matter how long it takes) which is the better battery to take? I talked to Tesla and the rep I spoke with said they are unlikely to switch over Sr+ Model 3s to LFP anytime soon in terms of new orders--this is really just a stop gap to allow people waiting a long time to take delivery sooner. Is the LFP superior based on factual data currently available? If not I'm inclined to keep waiting for my original order.

LFP battery in Model 3

There is no "best" choice, just a different choice. Do some Googling, searching, and reading and you'll find plenty of discussion on LFP vs NCA batteries.
There is a really (really really really) long thread here on the topic of these batteries in SR+ vehicles as they were launched in Europe a while ago. Emphasis on the "really really long".
MASTER THREAD: 2021 Model 3 - Charge data, battery discussion etc
In general you cannot determine the capacity of your battery from the charging screen. The energy added does NOT reflect the energy added. This energy is always just: rated miles added * (77.8kWh/~353mi). miles added multiplied by the charging constant (so it’s wrong, since displayed rated...

Yes but it is estimated. Real life miles could be much worse. No one will know until they get one and try driving it at 100%. But the real benefit is cycle life. You can charge it many more times without any impact to battery life. I would be wary if I am in extreme climate zones.

I don’t follow. 263 and 253 for NCA & LFP are both EPA estimates. So it’s an apples to apples comparison, no?

Those numbers are both at 100%. The issue is would you want to charge at 100% to achieve those numbers!
The current NCA pack does not like us to charge at 100% as a daily routine while the LFP can be charged at 100% at all times, daily, routinely.
So it's an occasional 263 vs the always 253.
The NCA pack has a realistic daily 234 (90%) range while the LFP has the always 253 (100%) range.
We have to baby the NCA pack and avoid 100% as much as possible while we don't have such worry with the LFP.

Thanks. I didn't appreciate the freedom from the 90% restriction until you enlightened me.
So living in phoenix I'd say I live in an "extreme climate zone" but I've only read issues with cold climates with the LFP. Have you seen that it might struggle with hot climates as well? we get over 120 here in the summer.

New Tests Prove: LFP Lithium Batteries Live Longer than NMC - OneCharge
Recent independent degradation tests of commercial lithium batteries prove - LFP chemistry is safer and has a longer life-span than NMC.
onecharge.biz
I think the pros for LFP:
.safety (harder to go up in flame)
.longevity
.durability (extreme temperatures)
It's not new. It's been old but Tesla did not use it because:
The cons:
.less performance (When Tesla started, it wanted to have an image of fast cars like Roadster, Ludicrous, Plaid... not slower Standard Range Plus)
.slower charging rate
.heavier (bulkier and takes up more space)

Something I found interesting with the LFP SR+ I owned for a while, even at 100% I still had regen

So im scheduled for delivery of my SR+ with LFP on the 7th. Im in MI. Why did I opt for it? Simply because Carvana offered $41200 for my 2019 Mid range, a car I paid $40K for in March 2019. Figured if I can drop it now, no telling what the market will do in the coming months.
I had a previous order that slipped from Aug to Oct, so I ordered LFP on 8/26. The vehicle said in Atlanta. I am in Atlanta. I filled out all the paperwork, got insurance, uploaded the insurance. Even went to see in the two local dealership if it is sitting in the parking lots. Nada. Today, crickets
I called the customer services today. CS rep pinged the vehicle and my car is on a train. Now I am thinking Cali - Atlanta? What's in the middle? Ida. Face palm. I am preparing for a longer wait. Too bad, because anytime there is a hurricane in the Gulf, few days later we have gas shortages in ATL. Sure it would be nice to have Tesla ready. Similar threads
