The original comment was about lithium and their popularity for backup power. Sodium ion batteries are so new that you can't purchase them yet (blueitte supposedly released the NA300 but I can't find any in stock and it's no longer on their site).
It wouldn't be fair to compare a chemistry you cannot purchase and which it's strengths and weaknesses haven't been tested outside of controlled laboratory testing.
Fair point - I'm not really that good with the physical sciences personally so apologies for my ignorance
You can buy them right now, there's more links in the 18650masterrace subreddit, but here's just one:

However good luck finding a BMS that works for it's particular voltage range, don't think AliExpress has any yet.
I haven't seen any posts from those diy type folks experimenting with them yet. Sodium ion cells just became available within the last few months or so.
