I do triple/60l/15gallon batches and wanted to do pressurized fermentation. Didn't care about yeast harvesting and wanted the simplest cleanest approach. I love stainless steel but not as much as the ability to see what's going on inside the fermentation vessel.
So the only logical approach was to get
Fermzilla All-rounder 60l. Cheap AF - invested rest of the money into temperature control, sparge water heater, iTap and other things which actually make my life easier and beer better

Just few days ago bottled almost 1bbl as I've got a second all-rounder now... things are getting out of hand
