Kosher salt is great as it’s less dense (which is why a lot of cooks/chefs prepare foods with it) - it gives you a finer control of how much sodium you’re adding to your food as you can crumble it into/onto your food.
The pink himalayan…yeah, I have it as everyone was touting its health benefits, but the mineral content is somewhat marginal. It’s not harmful, but I think the health benefits are pretty much an urban myth.
I had cut out table salt entirely…but a buddy of mine then reminded me that iodine is a good thing - so I use that in a lot of recipes now to make sure I’m getting that as well.
The Kosher salt I use is the Diamond Crystal brand.
Edit: Just saw @JustPeachy 's comment on the pink himalayan. Guess I’ll dump some into some water and see if this one has plastic bits as well…if so, into the trash it’ll go!
