This thread by far. It pushed me out of the 104 door and into the loving arms of 96, where I've been snuggly nestled ever since:

The 96 color palette is HUGE. More pinks and purples than you can dream of and all of the striking and reducing colors that I'll ever need. And I don't have to pay triple price for it. And the Iris Blue this month will be the same Iris Blue next month. And the best black and clear ever (Uroboros). No scum, no boil. I could go on for days, but I won't.
Tip: Flower Pot Saucers make great frit trays and they're very inexpensive. (Around 70¢ each)
