Yeah, electric is easier, if you can get it hot enough to cook in. If you buy electric make sure it has over an 800 watt heater element, or you may not be able to hot smoke in winter, even with an insulated cabinet. Some electric smokers are not insulated, but these typically have ~1500 watt heater elements.
Propane smokers will put out more than enough BTUs to hot smoke in the winter, even though they are not insulated cabinets. With propane you need to dial in the smoke chamber temp to what you want, and there is a slight learning curve involved.
Whatever you buy do not trust the factory installed door/lid/cabinet thermometer...they are notorious for not being accurate (off by 30-50*+) and need to be verified with another temp reading source. Most analog thermometers can be calibrated, so they're not a total waste, they just need to be tweeked after you get it home and set it up for it's seasoning and 1st smoke. Thermometers should be verified periodically, especially if you transport your smoker...vibration and shock can throw the reading off a lot.
I've never had the inclination to buy electric...don't think I ever will. Propane did everything I wanted to do back in the day...then I went to the dark side a few years ago and I've only cooked with charcoal since then.
