The one I used was this one (currently sold out?): http://www.amazon.com/gp/product/B00R421E8E/

No Halo effect, but you have to be extremely careful when applying it. Misalign it even a little, and you got yourself a halo.

After doing a ton of research here, on xda and rootzwiki, the best glass screen protector I came up with was the .15mm Icarez. Its fantastic. No halo effect, fairly easy to install, and they even give you a "kit" to remove dust and relift the screen if you mess it up at first.

And I absolutely loved my UAG case on the Note 3 and it was must to get another one. It has a great balance of durability without being exceptionally bulky. Extra padded corners and rear back, solid grips, it feels industrial strenght.
