First off, some of the plastic pry bars are needed. There are just too many things that get damaged if you don’t have them.
Note that most of the time you don’t actually pry with them, but push them progressively further under whatever you want to remove, and they work like a wedge. (e.g. removing most major internal trim / badges etc).
Sometimes you do need to pry though (popping out internal light fittings or switches) at which point you find out that there are different qualities of these.
At least one trim clip tool is needed. I’ve used the Snap On for a while, and it’s not only a solid tool, but all the edges are nicely rounded and smoothed so it doesn’t cause damage.
The downside to the Snap On is that it is thick, so using it on say a door card, you need to get under there with something else first. Note that you generally get under the trim AND the clip to use these.
The KTC is a lot thinner, and I find myself using this more. In fact, I have two sizes and three lengths of these now.
The plier type tools that darkzero showed are pretty much essential for removing the clips with a central pin. I don’t think anything else enables you to get the “pin” out undamaged!
I’m liking most of the trim tools I see by KTC. Pretty much becoming my default choice now. I’ve even grown to like the colour - it’s ”real world” practical if you’re removing black fittings and black trim, and placing your tools on black seats or black carpet!
