I have used this MSR stainless steel pot kit for probably 20 years, bike touring and we have used it for years car camping with the family. They really do hold up well from heavy use, and with biking I've used propane cannister stoves, as well as a Whisperlight that has been only used with white gas and as been reliable as anything.
I have pretty much the same set of stainless msr pots, mine came with the kettle and the pan is a bit different, and its only 15 years old. I used them in my kitchen while in grad school, as well as backpacking. While they have been heated with almost every type of heat source, from electric/gas ranges, campfires, alcohol stoves to canister stoves, they only have a few dents and will probably never wear out.
But like you I went to a lighter setup, with a Brunton Itty Bitty cookset and a pot cozy. Not as bomb proof, but SO much lighter.
