This arguement has happened a million times and will continue to happen. I my opinion it depends on a few factors. Size of plane: larger you go-better glow or gas is, because of the huge startup cost of large electric. What you fly, EDF jets are awesome and nobody(not many) use glow jets...or get a turbine lol= insane starup cost. The places you fly-I have no noise restrictions or size restrictions so I like large glow engines. What your comfortable with. Many grew up on glow. I personally love the sound and smell. Electric is like watching tv on mute. Your time commitment you can put in. If you fly once or twice before work go electric, if you want to do 4 or 5 flights in the afternoon go glow. Availability of glow fuel. If the nearest place that sells it is far, shipping glow fuel is rediculously expensive. I could keep going but that is it for now.

I have seen a few cost comparisons done. More often than not glow is cheaper as long as your plane is decent sized. My 74" glow plane would have cost twice as much if I did it electric. Especially since I already have equipment to support glow. It would have taken 340 some flights to make up the cost of electric, by then my lipo could have broken a few times so who knows.

Just my 2 cents!

Edit: lol just saw your post guess we have both seen this arguement before
