For me CI is the only way to go. I am fortunate that most of mine is all very old. I got several pieces, 6", 12", 16" skillets from my Great Aunt who's mother found them in an abandoned cabin on the top of the mountain that her family had. The story is that it was found around 1880, so not sure of the exact age, but to this day all of the skillets still work perfectly and have never had to re-season them but do work to follow best practices in the cleaning and re-oil. I always rinse with hot water, pat it dry put it back on the burner and and let the heat evaporate any addition moisture and follow that up with a light oil, usually Olive or Lodge spray and allow it cool down from there. I am also certain that the years of my Aunt cooking everything in lard helped these pans, and made some of memorable meals.
I am so addicted that when I was looking for houses I would not consider looking at one that at minimum had a gas stove option.
It does not cook like other pans and it can take time to retrain your cooking practices, but once you get there it is the best in my opinion.
In regards to overlanding, it is worth the weight to take just because of how versatile it can be, but if hiking i would not take CI but I usually would not have the same type of meal plans for hiking as I do when camping from the vehicle.
