If one buys batteries for a few decades they won't need a comparison guide. Most of the batteries these days have been around quite a while.
UK, here is my take.
Carefully measure the battery compartment and purchase the largest that fits.
Most often same price (or very close) but often more cranking amps.
On my CUT I actually doubled the CCA's for same price and that equals a few more years.
I just watched a YouTube video of the test guy (dont recall the name but he does a lot of independent product testing) where he compared batteries from Walmart, O'Reilly's, Auto Zone, DieHard and Optima. The Walmart did the best of all of them in price, CCA, charge time and lowest voltage drop during extended use.
I was really surprised.

I just replaced the one in my B2320 with Group 51R / 500 CCA from Walmart it was around $120 with the old one. I wanted a bigger battery but stayed with the same group for it to fit in the tray.
