So what's the advantage of liquid cooled over air cooled?

Much more robust cooling system and can run longer without worry of heat damage. Can also have larger engines and power producing capabilities.

Air cooled generators top out at about 24-26kw. Liquid cooled is hundreds of kw.

I’d be worried about an air cooled generator on a day like we’ve had in the past few weeks. 100+ temps and extended run time can be a problem.
