I went with manual flaps on my RV-3B (that's the default anyway) because I've gotten to like the ability to rapidly change flap position during landing. Especially to get rid of flaps upon touchdown when it's gusty in my C180. Because of that, I'd be reluctant to install electric flaps.
Still, a C180 isn't an RV, and a taildragger isn't a nosedragger. Those differences might legitimately affect a decision.
I'd expect, without data, that electric will be heavier. Don't forget to assess the additional electrical control and sensing and wiring compared to the manual system. It does free up some cockpit room, though, and that, too, might be worth considering.
