If op is buying one or another, then a leisure battery is the way to go.

I do agree with you, but it depends one what someone can afford. for a new racer having to find another £80+ for a leisure battery may not be everyone's priority if they have a spare or old 12V laying round that they can use, which will work perfectly fine if treated well and kept charged.

I stick £100+ leisure batteries on my boat to start the chevy 5.7ltr 325hp V8 lump. The last one went dead over the winter, when it was deep discharged...
The old BMW Bosch battery works fine to charge a few packs at 7A.
