I love the synapse tiagra 2014. As my first road bike, and only having had a hybrid before hand, I don't know why I didn't get a road bike 6 years ago (when I started cycle commuting). I have nothing to compare against really, but it' is light and has smooth gear changes.
First few rides I had lower back pain, but I think this was just me getting used to the different riding position compared to my 'sit up and beg' hybrid.
I was unsure about a white bike to start with, but the colour has grown on me. It looks so 'fresh' and I think it is easier to clean as you can see al the dirt.
Here is a pic taken 3 weeks ago when it was new. Only difference is the handlebar tape is no longer white, more of a light grey And i put a new saddle on it. (charge Spoon):
