My beef against SRAM is the slow shifting FD and frequent chain drops. It's a big no no for me. If you don't know what I'm talking about by slow shifting, go try an Ultegra or DA DI2 FD and compare.
Even with a magnet tool, it's still a challenge. Building up a bike from parts is only a very small portion. My biggest issue was when a customer brought in a LBS bought bike with a Di2 issue. Usually it was just a wire that came unplugged from the shifter. But there were times when having to replace a wire that went from the battery to the rear derailleur. Those were the ones that drove me nuts.
