Advice: Retouching kits

I know this is loosely related to 'large format' but this community is a decent bet. Feel free to remove mods

It’s been a good old time since I’ve had to do any retouching but I’ve just been doing some big 1mx1.5m prints for an exhibition and they require some work. Why is another discussion entirely…

The question is what is everyone using these days?

Berg touchrite looks to be the biggest in the game right now.
