The gravel thing is an odd duck, it is picking up steam around here too. I don't fully get it, but last year I met up with the guys from Poseidon bikes. They make some very inexpensive but great bikes. I now have a "flat bar gravel bike" that really feels like a MTB from the 90s. It's fun, I do ride it to cross train on a canal trail system and some of the trails too. I do recommend them now to people that ask about gravel but aren't ready to drop big money. It's fun for that, but it's about as far down the gravel path as I can see myself at this point. I'm sure that Giant is a great bike, just choose a build level you're comfortable with and do it.
