I think the Botania one (Botanical Brewery) is nice - a single step, instead of multiples, and a vial or flask containing 4 or 6 doses of the potion instead of 3 non-stacking single-use potions.Botania and Blood Magic both offer options for potions. I've not used them since 1.7, but I don't remember it being overly tedious (although the opening to Blood Magic was a bit rough at the time). The Blood Magic potions are strong and can be used multiple times.
Depending on the potions you want, an efficient Witch farm could provide a decent supply.
