That Vanguard trigger is better than the 700's, plus that Vanguard is deadly accurate.
I have shot both and I own a Vanguard, it's heavier than the 700 for sure, but all that weight's in the barrel.
I'd pick a Vanguard between those two without hesitation. And if you can adjust that trigger to your liking, put a Timney on it.
The Vanguard I dry fired in the store had the grittiest, creepy, long travel trigger that I have ever pulled. And that was the model where their advertisement said they go over each trigger. Bah. The Remington I dry fired in the store was one of the best triggers I've pulled (other then a premium Timney or Jewel trigger).
