For me, only electric. Having my plane set up in under 5 minutes, clean, consistent power (yes, with the modern cells it is very consistent). Packs getting cheaper and better every year, the airframe lasts for ever, servos do not wear down by vibrations, no complaints about the noise from anybody... I can understand why people like/use glow when they have a lot of experience and lot of money already invested in the equipment. For newbies though, electric makes much more sense, imho.
