Any toolbox/bag with your favorite items in it.
If it was a present for someone, then an all in one kit would make better presentation, but if its for you why limit yourself to a single brand.
What do you think you need. For a quick 15 minute detail all I use is a quick detailer, tire gel, window cleaner, and a selection of microfibers.
The only thing on that list that isn't always in my car anyway is tyre gel.
