I have collected a bunch of cookware over the years so now I choose what I need depending on the scenario. For lightweight trips with backpacking food I carry a Ti mug, a Sqishybowl, and someone in the party carries a large cooking/wash pot. When out with the scouts I carrry an old BSA messkit, a truly well thought out design. Other times I will bring the mini Trangia, day hikes will fing the Swedish messkit.
For cooking over a fire I like a SS Nalgene bottle cup with long handles or a SS mucket, a 2l Zebra billycan, and a light steel frying pan (forgot the brand) and sometimes a plastic eating tray.
My most recent purchase is an Optimus cookset with the included neoprene cozy. I have not used it enough to form an opinion on it. For car camping with the family we take an MSR mountain cookset with heat "exchanger" or an Open Country cookset.
