I share a lot of common opinions on these weapons. The Inkbrush is extremely potent on turf wars, provided the map isn't something like Moray Towers, and the Octobrush picks up after the Inkbrush's lackluster range and damage. I find the Inkbrush Noveau to only be useful over the classic on tightly packed levels like Kelp Dome and Port Mackarel. The Octobrush is imo a lot better, were it not for the ink efficiency. The Kraken is always super good! xD
