I think it's really about what you prefer. The new 6800 mechanical system is really smooth and low effort. The electronics, of course, give perfect shifts every time. Personally, after putting decent miles on both, I settled on the mechanical system because of cost, but also because I actually like the more direct feel of a mechanical system. Of course, I drive a stick shift car daily as well. Others love the electronic setup for the tech or the lack of adjustment and cable maintenance, etc. I have heard that replacement parts for the electronic system are expensive and sometimes hard to get, but that could be wrong, so don't take it to the bank unless someone else can confirm. Bottom line, it's up to what you personally like. No bad choices here.
