I have both the Arctic (~900mW) and a yobresal (~1.1W) and much prefer the yobresal build.
It's not huge like the Arctic, doesn't have the annoying smartswitch, it has 3-modes (low pulsed, high pulsed, and constant), and it's focusable for serious burning.
Not to mention it's 1/2 the price of the Arctic, much more power and you will receive it in days not months.
