That list looks to be pretty much in favor of LiFePo4. Highest energy
density is only one factor; overall practical use I would judge to be
more important, and safe.
This view has been widely accepted, and LiFePO4 is the de facto standard
for replacement of other nominal 12V chemistries. Bioenno Power sells a
wide range of battery packs, and is very ham friendly. Pre-COVID, they
have exhibited at ham conventions. Last I heard, they are being marketed
by Ham Radio Outlet.
I own two of their 20Ah packs for portable use, and one of their 100Ah
packs has been running the two K3s on my operating desk for almost five
years.
With ANY Li chemistry, including this one, it is critical that they be
charged using a proper charge regulator. I'm using a Genasun solar
regulator with a re-purposed Thinkpad PSU. Genasun regulators are RF-quiet.
