To me, someone who celebrates a bit more of the spectrum than most: Metal hot. Make food hot.
Non-stick means easier cleanup, but my wife seems to think cast-iron is necessary for certain things (searing a prime rib roast, for example.).
After I figure those out, then I gotta figure out gas vs. electric vs. induction vs infrared…
If your seasoning rinses off with mild soap and water, you might want to try some different seasoning methods. That might mean using a different oil, different temperature, longer heat time for the seasoning, etc. Or you might want to season it with thinner layers of oil multiple times in a row.
