As someone that mained a PVP hunter for nearly a year and has been playing Sunbreaker off and on for the past week, I can without a doubt say that Hammer of Sol dumps on either Golden Gun or Arc Blade. It has far more time, far more damage resistance, comparable mobility, a regen ability, is easier to land hits with, and comparable range to GG (for all practical purposes at least) and more than AB. Setting aside the insane armor the super grants (tanking sniper headshots, GGs, & rockets) it still has a far greater ease of use and destructive capacity than either hunter super ever had. Hammer of Sol (among other things) makes me wonder if Bungie even playtests content before releasing it.
