The Netherlands mostly had rebellious warfare and although we conquered quite a lot around the globe, we did so with trading, mostly.
I can't really pick a regiment I can say I am particularly fond of, simply for the fact that we don't really have nor had awe-inspiring regiments. (Not saying the guys back then didn't do their job, we just don't really have famous regiments

)
If I do have to pick, uniformwise, I would go with the scarce and tiny regiment(s) of the Byland Brigade at the battle of Waterloo. These uniforms are still sometimes used during re-enactments and processions.
