105 shifting was quicker, but 2x8 was more precise, especially when cables/housing gets a bit older.
My conclusion was it was down to cable pull and cog spacing. Since the 105 RD was top class.
Not sure why the perceived difference is that we both experienced, but from my experience the 105 is definitely better all the way around. There is one thing I need to mentioned that I failed to do so. I test rode bikes with all 105, based on those test rides it was better than Claris, my bike however has Ultegra rear derailleur not the 105, everything else is 105 except the cables which are DA9000 cables, that system setup is a day and night difference against Claris.
