I've found myself more and more absorbed into Glitch, obsessing over leveling my character as much as I can, and I've found myself confused.
Quoin upgrade cards make purple quoins better, and only exist to increase future img gain from them. Unfortunately maxxing out quoins for the day is rather boring, and I can't tell if the Jumping Quoin Islands are more profitable or doing a loop through The Drop.
Energy upgrade cards don't directly increase your img gain, but do allow you to do more within a span without having to recharge. It's nifty for crafting large chunks of seasoned beans at a time or seasoned eggies. The cards also provide a free energy refill when you buy them, and increase the img gained from singing to butterflies (and perhaps, more scaling activities?).
So the question is, which cards are better for a power-leveling-son-of-a-glitch with dreams of the big 6-0?
