What I meant to say is that your gun does not have as big as an impact as you imply. Especially given the fact that virtually any endgame gun is going to have around the same reload speed (all MyShop/Gacha, Powerful, Altiverse, Uniques, and I think Ultimates too have around ~1s reload).
@Gabby: I don't know if it's both Keen Sense and Gun Overdrive that you need to make your timed crits stronger than Powershot or just one. I'm fairly certain Overdrive by itself will make them stronger, but I don't think Keen Sense by itself will. Not to mention you have to get hella good at it since a missed crit is a loss in dps ;o;
