Both bikes are great at that price range. Can't really go wrong.
Allow me to throw KTM into the ring, if you'd be ok with buying online (or you have a dealer nearby). They're new to the US, so just starting out here but they've been around a LONG time. But the
Rev Sky Blue looks stunning in person and yes, while it's equipped with 105 components, I can assure you you're getting the better frame with this bike. They have some other options too if you care to look around and you can chat with the staff and ask questions to find the perfect bike/size for you. I ride a Rev 3500 and it is the most comfortable bike I've ever ridden and I ahve ridden a LOT of bikes.
