Well, no not really. Middle of the block means the chain, cassette and chainrings should wear slower as the chainline will be straight most of the time. Also more efficient, less noisy etc.
It's personal though I suppose. I prefer to change the front more often than be up and down the block all the time - that bike (53:39) does have di2 though, so front shifts are no more effort than a rear.
