The biggest practical difference is form factor: these aren't the same kind of device. G Pen Connect is a portable, Ruby Twist is a desktop. Pick based on whether you want something portable or something stationary.
G Pen Connect uses conduction heating, while the Ruby Twist uses convection. Heating style influences flavor profile, vapor density, and how forgiving the device is to draw technique.
G Pen Connect is the take-anywhere choice. It's a portable, battery-powered unit, while the Ruby Twist is built for home use, where bigger heaters, AC power, and larger chambers make sense.
Listed prices are close: $180 for the G Pen Connect versus $170 for the Ruby Twist. Day-to-day price will likely come down to whichever retailer is running a promotion.
