I have pic related, allez comp 2016. As much bike as you'll ever reasonably need in my opinion. Wheels are heavy but strong and seem durable which is good for winter use. My Cyclocross bike is previous gen (10 spd) 105 which I'll stick my neck out and say is this years tiagra and it works well. AFAIK the geometry of the frames is slightly different between the expert and the comp, the later having a better fork and lower stack headset for a more aggressive position.
