Get both. You sound like me to a tee. I bought my Trek in April and My Giant 29er 3 weeks ago. Love'em both. Do trails with both. Do long distance on road with both. Each is better suited for road and trail respectively but both are a ton of fun and are cross-functional to an extent. The 29er is fast, and the Trek is tough.

I got the Giant primarily so that we had two quality Bikes that were different but both capable enough to do just about anything except hardcore mountain or road biking so my sons can ride with me.

For $1100 I got two great bikes that can do 90% of what I and most bikers will ever need. Less $$ than someone would pay for one low end road bike.
