I have Superior and a number of the Toontrack add-on's such as Metal Foundry, Music City, C&V and also some Slate Drums, CLA add, etc... so those are my general go-to's for drum kits. Have a number of the EZ Kits but generally use the Latin Kit or the Electronic kits. They provide easy access to some sounds that may not be available in other kits, all-in-one. Very useful. Occasionally use Nashville, Jazz or Pop as well. They are all pretty decent. It really depends on the style of music you are doing. For Pop, Rock and Folk, certainly Latin could work in any of those genres and Electronic is useful for Pop. I often use the Kicks from the Electronic kit as a 2nd Kick in Pop or Rock songs to give it some more bottom end and dimension. If you are looking for your main go-to kits, these probably would not be your best choice. As enhancement for what you already have, something to consider.
