FWIW... this got me a little curious...
Seems aluminum build practices from around the 80's and now are quite different! Guess there were a lot of issues in those early offerings that have changed the alloys used today in frames etc... now the weight delta is much less. Like maybe only up to 10-20% and that's really not much (matches what you report seeing).
The basic summary in my few minutes of reading various tidbits was that I'd probably buy steel today unless there was some other factor of great importance to me. The only thing I can think of is corrosion but they both corrode in their own ways and environment reactions so that would be low on my care list relative to the fact I don't usually keep things longer than a decade.
