There is only one brand of "whole juice" kits. That's the Mosti Mondiale All Juice brand. I haven't made any of these, but based on comments here at WMT it's good but not the best.
There are some brands that are 23 litres of juice/concentrate mix, and they vary in quality from 'standard' to quite good.
Otherwise, the kits are concentrate only, concentrate/juice, or juice/concentrate. Generally the smaller the box the more concentrate.
To answer your original question, I really like the Ken Ridge Showcase and Cru Select brands. The En Primeur, Cellar Classic Winery Series, and Cellar Craft Showcase also get consistently good feedback, but I don't have much personal experience with them.
There are specific other kits that I think are very good (eg Ken Ridge Classic Merlot), but you were asking about brands.
The limited edition kits that are produced are also usually very good.
