Candidly, they all are (reliable), at least the ones that cost more than a couple hunderd bucks. They all have the same guarantee which has become the insustry standard so it becomes a matter of personal preference. I like Vortex optics in general, but then I have many brands.
My least favorite of the lot is the Nikon. The magnification rings on Nikon's are too stiff for my liking.
Get down in the lower price point anf you have warranty issues. Nothing warranted after the purchase. I don't need a non functional scope for an extra powder funnel.
