Most of my dies are Lee. The belling/expander and factory crimp dies are top notch, but as mathman stated, the sizers and especially seaters are definitely not on par with the higher tier brands. If you are a real burr up the azz type stickler for seating depth consistency, Lee are not the dies for you.
Make sure you clean them out before you use them, because metal dust/shavings are fairly common. I've gotten a couple dud dies right out of the box over the years, but they've replaced them with no hassle both times.
I'm not a long range or match shooter, so they're fine for my purposes. 🤷♂️
