IMO, If you want it to work ALL THE TIME, Every Time. Dont go electric...If you want to invent swear words never before heard by humans because the bleepin thing doesnt work, then by all means go electric.
If you want it to work ALL the time, in any & every condition. Hydraulic rotation is your friend. I know last year mine was caked with Ice, frozen solid on more then one occasion and it always turned smooth as silk.
Think of it this way...if electric rotation was so great and worked so good, every snowblower MFG would offer it.
