I recently purchased a bike with 105 di2, but it came with a Shimano non-series crankset. I replaced the crankset with the 105 7100 before riding the bike because I knew that detail would bug me forever. Compared to the older gen 105 cranks, these are more angular and modern in appearance. From a distance, they look identical to the new Ultegra and Dura Ace cranks. Other than that, these aren't too heavy and aren't too expensive - what you expect from 105 components.
