Optima or Yuasa?

[lc27]

Hi guys
The time has come to replace the batteries
I got a couple of yuasa actually they last 8 years, so no bad ah!
Looking at the options the yuasa website suggest two models
YBX3334 700 amp £162
YBX5334 800 amp £182

On the other hand I can’t figure out which optima model would fit the LC and quality of that battery

Looking at bills, I paid £98 for the yuasa 600 amps 8 years ago

Any idea of which optima model would fit and if it worth the change in brand considering how good the yuasa was?
Regards
M
