This is a very subjective answer and it really depends on personal preference.
The Brew Bucket has a conical base on it, so in theory (and in practice) it greatly reduces the contact patch between the trub/yeast pile and your beer.
This means just like with bigger conicals, you can rack off clean beer right from the primary vessel instead of having to rack out into a secondary. Of course, there are folks that may feel they get better results still racking off their beer into another Brew Bucket (or a carboy or whatever) for their secondary fermentation.
We don't advocate that either approach is right or wrong. Just like all things in brewing, there are many ways to make good beer and just like golf, it doesn’t matter how you get there, just where you get to!
