Well I brewed a hundreds or more beers in buckets, still use them occasionally. Few years back Went with a fermzilla to see if I got anything more from it. So it can do pressure fermentation which is a plus but the main advantage to a conical is you can get at the yeast for a repitch before the beer is done fermented. Fresher the better. I like the fermzilla because you can see when the krausen starts to drop when adding hops. I also have a basic SS Chapman 7 gallon bucket fermenter which works like a regular bucket . A lot less cleaning involved .
