My apologies for not reading every post - especially if this point has been raised. My opinion coming from a shifting perspective of friction, Ergo and Di2 w/discs all in my current riding group - and simpatico with each technology.
Once you get used to any or all styles of shifting (given the 'needs of your ride' requirements) - I find it to be just as much a matter of hand comfort on the hoods, as the actual shifting itself. Narrowest hoods on friction, wider on integrated, widest (on many groupsets) on integrated with hydraulic disc.
I change hand positions a lot throughout most rides - so while (brake) hood size/shape isn't directly a shifting issue - it may be a consideration affected by the tech one selects. IMHO
I prefer narrow. Not a necessity for every ride, but...
Levers are always prettier in silver, fwiw.
