It depends on how much you ride, how ADHD you are about shifting, and how you feel about bike maintenance versus charging batteries. Remote shift buttons may be a killer app.

I get 8-10 weeks out of rear shift cables before breaking strands with contemporary brake/shift levers integrating a tight 90 degree guide for under-tape routing using hoods hoods level with the bar tops.

Electrical cables don't fatigue with each shift or go high-friction like mechanical housings.

I'd buy electronic shifting in a heart beat if I didn't do my own maintenance or was building a time trial bike.
