The wired vs. wireless aspects have their pros and cons. For Di2 I didn't consider it any more or less difficult than running derailleur cable. For most people the brake hoses need to be run inside the frame so you are there anyway with the tools needed to do the job in hand.

When comparing prices you do need to consider the extra cost of cables and junction ports with Di2. Including a battery, charger, ports, and cables, all that cost me close to $500.

Sram batteries and chargers aren't cheap either and need to be removed for charging. All the wireless communication hardware is built into the components which adds to their cost.

In my opinion neither one has the advantage.
