Pocket Infinity and Plan C were the best but you already know that.
My favorite was 77 Wizard which was the original Crucible one. It was a slow charge with crazy impact which is my preferred type. The quick-charge counterpart at the time was LIGHT/BEWARE, which was a favorite for a lot of people.
Following Vanilla, Plug One.01 was a solid compromise between the two, just about any roll of it could be useful from one like you had for quick firing or one I had with range perks. Give/Take Equation kind of replaced that for me in HoW, it was also balanced and had a super tight beam. Final Rest II and The Trolley Problem had crazy range that made them pretty dominant on the right maps. Perun's Fire was the champion for the quick charging ones, when rolled with Acc. Coils it had the fastest charge in the game. Also, Light of the Abyss was all around great with a huge punch for how quick its charge was, and some fun shenanigans with skip rounds.
