I gotcha, I used a NEX belt for a little over a year of daily carry. I won a Tier One KORE belt 2 months ago at an event and have used it daily since then, and it may seem trivial, but I like it ALOT more than the nex belt. I think there are a few small differences that make it better and more comfortable.
1.) It is slightly wider and it appears the hard material is slightly thinner, getting more of its thickness from the fabric and neoprene like material on the inside. This makes it "feel" more cushy and doesn't dig into me as much as the nex belt. The nex belt some days feels like I'm wearing a ratchet strap.
2.) The buckle is longer and thinner, as opposed to the blocky square nex belt. The way I wear my belt, the nex belt would either pinch my skin against the holster or it would ride on my hip bone(I'm 6' - 185). I like the longer buckle of the Tier One
3.) The inside of the Tier one is stickier so it doesn't move around as much. This makes it harder to adjust but I only adjust a few times a day, so having it stay in place better all day and be more cushy is why I like it better.
I had an original Springfield XDM 5.25 match pistol that I loved. It was flawless for 3k+ rounds and I regret selling it. That being said, I've shot 10 or more various Springfields since then and I've hated them all lol. My buddy just got the Hellcat pro and I don't like it. Feels ok in the hand but shoots noticeably worse than my Sig 365XL.
