The biggest practical difference is form factor: these aren't the same kind of device. G Pen Elite II is a portable, IO Hornet is a desktop. Pick based on whether you want something portable or something stationary.
G Pen Elite II reaches session-ready temperature in ~30 seconds, while the IO Hornet takes 3-5 minutes on a 16mm coil, longer on 20mm and 25mm adapters. That's roughly 210 seconds quicker on the G Pen Elite II, which is useful if you want shorter, on-demand sessions.
G Pen Elite II uses hybrid (primarily conduction) heating, while the IO Hornet uses convection as an injector, hybrid with conduction as a diffuser. Heating style influences flavor profile, vapor density, and how forgiving the device is to draw technique.
G Pen Elite II has the larger chamber at 0.3 - 0.5 grams, versus 0.08g to about 0.2g, around 0.15g for a full draw on the IO Hornet. A bigger bowl means fewer reloads on long sessions; a smaller one suits microdosing and quicker bowls.
G Pen Elite II is the take-anywhere choice. It's a portable, battery-powered unit, while the IO Hornet is built for home use, where bigger heaters, AC power, and larger chambers make sense.
Listed prices are close: $250 for the G Pen Elite II versus $260 for the IO Hornet. Day-to-day price will likely come down to whichever retailer is running a promotion.
G Pen Elite II controls heat with digital control, while the IO Hornet uses set on a separate pid controller, included only in the complete kit. G Pen Elite II gives you finer per-degree control.
