I like to avoid the hassle of taking special care of a cast iron and just use a stainless steel pan from IKEA. Spray on cooking oil works really well to keep food from sticking if your don't crank up the heat and anything that does get stuck can be easily scrubbed off with a copper scouring pad. Best part is that there's no need to worry about rust. Ultimately just use what you like most.
Especially for steak, pork, and fish, the cast iron heats up better and sticks far less than steel. Also much easier to clean.
But for anything that's saucy (pasta) or could benefit from a good deglazing (scallops particularly but also for veggie dishes), stainless steel works best.
I just have to commit myself to cleaning up immediately after the meal or consign myself to a lot of scrubbing.
I like to have both on hand. Really depends on the dish.
Hey, if your meat is sticking it might just need to sit longer at a slightly lower temp if you are worried about burning. Letting pork sit for longer has done a lot for me for it sticking.
And then also for cleaning heating up the pan dry on the burner than throwing in some warm water to boil while scraping the bottom has been way faster than scrubbing it all.
