I find the splatterscope more comfortable to use than the splat charger--it charges quickly enough that you can quickscope very effectively with it, and I feel like charging when you're about to shoot instead of keeping the gun charged is the best way to use the splat charger. The extra range from the scope doesn't seem like much on paper, but it can actually make a big difference more often than you'd think. I usually prefer the regular E-liter over the scoped version, though, because the slow charge time means you need to keep it charged and ready (and, with a scope, zoomed in) more often, which is an easy way to get yourself killed on most maps, unless you're able to keep an eye on the screen and an eye on the gamepad and you're very aware of what's going on around you.
