Welcome to the madness!
In my humble opinion they are both different animals. For me 711 is a great camping/woods knife provided you have something smaller for finer tasks, say Scrapivore.
R6 is a bit better balanced, with the full tang, and could do in a pinch as a one only knife. When you get it in your hand you'll feel that it is not a 'combat' knife.
If you wanted more versatility at a somehow higher budget go with 911 & R4. Don't think there's anything those two could not handle! (aside from sea water...)
Just my 2 cents...
