I only buy krusteaz for pancakes. I don’t really think the amount of effort it would take to hand-make a similar batter would be worth it, nor would it taste remarkably better.
Though, for actual food, I have the same sentiment as you. I like to cook and experiment, and I have a fairly easy time adjusting things by taste, but I don’t have the time/energy/money to be doing everything from scratch.
