7mm Rem Mag Comparison + Advice NEEDED

[Lopas07]

Remington 700 XHR 7mm Rem Mag.
vs.
Weatherby Vanguard 7mm Rem. Mag.
vs.
Browning X-Bolt Composite Stalker

I am thinking about a new rifle and am in need of advice.
I am looking for a 7mm rem mag but don't know whether to go for Remington, Weatherby or Browning.

I know Browning and Weatherby are great rifles but havent heard much about the Remington brand at all.

If anyone has some advice it would be greatly appreciated.
Thank you.
