Giant toughroad slr 2 2017 vs Specialized sirrus elite 2017

I need a new commute bike and both bikes are pretty similarly speced what is people's thoughts on both bikes. Usage will comprise of upto 18 miles a day commute with some occasional off-road gravel path riding? Is this a case of both bikes being the same and just having a do all set of tyres? Many thanks folks

Much better specced than the two above for only a bit more cash, I reframed my old Carrera Gryphon based commuter into an LR frame and am really happy with it, low front end (I run the stem flipped), fast and responsive yet absorbs the bumps well.
It will come in about 2-2.5Kg lighter than those other two.

I'd take the PX LR with Rival groupo versus the cheaper Apex on the Sonder at the same price.
