You didn't get this advice from the FB group did you? Because the next next bloke recommends metho... Anyway.
Neither will sterilise, but will sanitise. The difference in sanitising is that almost everything is killed. Sterilisation is a 100% destruction of all living cells, usually via high heat and pressure treatments (ie autoclave or ovens).
I use a no rinse sanitiser, but prior to that I'll clean with whatever is appropriate at the time. That might be detergent and a cloth, or sodium percarbonate, or bleach, or a iterative combo of some or all. I don't think I'd use an all in one cleaner/sanitiser, and I don't think an all in one product would be superior to anything else, but this is just yet another opinion from some guy on the interwebs.
Advice? Clean well, use starsan.
