I have the Vortex 4-16x50 FFP mrad EBR-1 and have been very impressed with the scope. The glass is really good, the zero stop is handy and the .1 mrad clicks and the amount of hold over available before dialing is great and NO Math required.
Having said that, I've not used the Weaver nor had the Vortex past 350 meters. Here in Banterio Canada the Vortex was in the 900 dollar range, likely much less in the US.

Just for reference if it might help you...the mechanical zero was very close, as in 11 mrad on a total 21 mrad adjustment come up. Similar on windage. With a 20 MOA EGW Picatinny rail and a 100 meter zero with Federal factory 165 Gameking and Fed Factory 168 SMKs(both had same zero) on a Rem 700 SPS Varmint I had 18.8 mrad come up to the stop at top end.
