CAT JL Ti vs Inconel?

I’m looking at the JL for an AR10 platform 308 build. 18” barrel ,PRS stock, adjustable gas block, more of a quasi precision build. I’m considering the JL because I can get a good price and trying to decide between the two. Right now I’m new to longer range and just doing some bench shooting, but have a class line up for long range and eventually would like to get into being able to do shooting from different positions. There’s not going to be long strings of fire with it. I’m leaning toward Titanium for the weight savings once I get to a place where I’m competent enough to do some moving to different positions and shooting — if that makes sense. Thanks!
