The electric motors tend to be quieter and also weaker. But there are also newer models that are more powerful. And they do generate noise, but it sounds more like a hushed vacuum cleaner rather than the typical leaf-blower sound. If you want to hear the difference check out this particular timestamp of this comparison video (https://youtu.be/UUQeGzGy0Ds?t=397 https://youtu.be/UUQeGzGy0Ds?t=397). The gas powered blower is ~5 dB louder at peak. The electric one is at 78 decibels peak (max power with "turbo") but the gas powered blower measures at 78 decibels just idling. The reviewer notes that the electric one is very bearable for him as an operator, but the gas powered one is too loud to think clearly. That particular model of leaf blower with the backpack is fairly powerful, and the reviewer notes it pushes more air than the gas powered one he is using. However, a number of comments mention that the gas powered blower is much more powerful and that the reviewer is biased, which may be apparent from his early praise for the electric model. The big issue is that the electric blower's runtime is limited. He gets 22 minutes out of a full battery using it "normally", which takes 1 hour 40 minutes to charge on the standard charger, and 42 minutes on the fast charger. He concludes that electric is better in every way for homeowners, and there's no reason to go back to gas unless you are a commercial user (presumably due to the battery limitations).
