It's the same engine.
If you want to keep your options open get the GT15 and buy a spare 1/4" cyl. head or glow plug adapter.
Another option is to get the GGT15 and add an aftermarket RCEXL 1/4" CDI.
If cost is not an issue get one of each...
The ignition engine will be heavier but have a bit more power and a slight fuel consumption advantage.
