LiFePO4 - SOK or Renogy.
Not looking for a big bank or high charge/discharge currents. Don't need charging below freezing. In Canada things become difficult/expensive. Narrowed down to these 2: 1)SOK, 100AH, $CAD 975 ...

Thanks. The Lynac 100AHs are out of stock right now. Preorders only. I subscribed to your testing thread to learn from your experience.
The fact that he answered your question immediately is a good sign.
My wife recently got a CPAP. We were going to power it off grid with a so-called solar generator but figure the money might be better spent upgrading the house battery in our rig.
Many camping items have disappeared and/or prices jumped up in April-May.
Solar generator is an overpriced combo of Li battery and inverter, $CAD 1,400 for 1,000 WH. I paid $CAD 800 for 1,500 WH, i.e. 3 times cheaper per KWH. With a single 1,000-1,500WH battery you don't want a big inverter, nice 300-400W PSU inverter would cost less than $CAD 300 and I already had one.
It does take 200-300W solar to keep it topped up, but for a weekend with modest loads you just discharge battery down to zero and go home. (Actually down to DOD 20% in my case, since it's 120 AH marketed as 100 AH). What I particularly like is 30 lbs weight - much better than 70 lbs FLA or AGM of the same nominal capacity (not to mention 2 times less of usable charge).
