Shimano has not updated the 4700 derailleurs since they were introduced in 2013 and they are getting very long in the tooth. The 4700 front derailleur’s outdated long arm design has too much resistance against small trim inputs so it doesn’t trim as nice as the current 105 FD-R7100 toggle-type front derailleur, and the 105 RD-R7100 rear derailleur has a stronger return spring than the old 4700 knuckle rear derailleur so the R7100 keeps the shift cable more taut with less cable slop through the complex bends in the under-the-bartape cable routing so the cassette shifting is better.

A future upgrade for you to consider: [Replace those very old 4700 derailleurs with the latest Shimano 105 R7100 derailleurs.](https://www.reddit.com/user/joepublicschmoe/comments/1hjojd5/confirmed_10speed_tiagra_4700_shifters_compatible/)
