Also, just out of interest, and in keeping with the WW way, I weighed the bike today - 7.47kg in medium/large with two bottle cages and pedals. Not bad for a bike that cost £1350 plus £650 for the wheels, and I have a brand new PR-2 wheelset and tyres which I'll hopefully sell on Ebay for £200, so all in all about £1800, so lighter than the Advanced Pro 0 Disc and HALF the cost.
Hard to justify the disc brake model with that kind of cost/weight penalty, unless you ride all the time in the rain or do a lot of urban cycling IMO.
I don't think it's really fair to compare the two bikes you're comparing on only their weights and saying the rim brake bike is better for half the cost. It's probably better to compare the rim brake bike with the disc bike that is closest in spec: the TCR Advanced 2 Disc (https://www.giant-bicycles.com/gb/tcr-advanced-2-disc
). That bike is £300 more than the rim bike you're looking at and, apart from the disc vs rim differences, has the same level of groupset, wheels, frame, and fork.
Before I bought my 2017 TCR APD, I rented a 2017 TCR Advanced 2 (rim) for 4 days. So basically the 2017 versions of the bikes you originally posted about. I rented the rim version just to see how I liked the frame, geometry, etc. Then I bought the APD a month later. For me, the APD felt loads better. Some of that was due to the better stock wheels (which you are adressing), some was due to the better brake feel (but you seem perfectly content with rim brakes, so that's not an issue), some is due to the Ultegra DI2 vs mechanical 105 (for me that was HUGE, but only you can decide for yourself), and some was perhaps due to the other upgraded parts (stem, bars, carbon steerer, etc).
If all one cares about is light weight and 105, then the A2 is a no-brainer. Some of us want other things which more than justify the extra cost of the APD. I would never have bought the A2 as an upgrade to my Cannondale CAAD7 (with Ultegra 6800 group).
