I don't have a good answer for a good crimper, but I found a really good wire stripper.

Easiest and best wire stripper I've ever used .
Here's a pic of the one
@Big_John mentioned. Looks like a more automatic/updated of an older spring-loaded style from 15-20 years ago that somewhat resembled this.
I did not find the older version to work that well, as you had to get the wire in the correct-size die for a proper cut - all the thing really did was pull the cut insulation off for you.
But this one looks like it has more functionality, and I would trust
@Big_John's endorsement.
At my latest job where they have an electronics shop and do a lot of hand-assembly, they have these.
I had never seen such a type before, and was amazed at how well it works. They are ~$120, though.
Amazon has some knock-off competitors, and some of them seem to be from reputable names in Germany?
All depends on how much time a guy wants to spend researching, though.

It seems Klein still makes the older type of stripper.
I circled in red the dedicated die cuts for various wire gauges.
Put the wire in too-big die - it shaves the insulation.
Put in too-small - it can cut some conductors.
And for every strip, you must have your hand all the way open.
The Weidmuller I showed is much more ergonomic than this Klein type.
