Possibly getting a little technical but the last lot of Maxell UR available outside of Japan was made by PT Panggung, had been since about 2010. It's decent but you cannot record above 0dB as that's it's saturation point and you do need fine bias adjust. It needs a good deal of negative bias to get the best out of it. So put it in a machine without fine bias adjust and it will sound mediocre for sure. The new stuff is now on the Japanese market as Maxell UR but hasn't been released outside Japan. It's decent again, but not the UR of 1990.
I've seen the thing with old geezers who went for new technology getting jealous of those who stuck it out with older tech (or tried and retained both). I have it in the world of vinyl records where I never dumped any of my vinyl nor turntables....so today I am in the enviable position of having my record collection, having snapped up bargains in the early 90s when everyone was offloading what are now valuable records to "upgrade" to CD....and having kept my and my dad's previous turntables. Thus I have a lovely Systemdek at home, a moderate Sansui in my office and spare copies of many a lovely record acquired for peanuts. And the people who ditched records only to try and return a couple of decades later are sometimes jealous, even angry.
I can well see film being similar. Oh...another anecdote, I was taking a stroll around Wrest Park a few weeks ago with a Lubitel TLR while my partner had a Voigtlander Brilliant. A chap stopped us for a long talk about TLRs and about how he gave his to a museum 20 years ago and now regrets it because he can't afford to buy another Rolleiflex. He wanted to know how good the Lubitels are as he wanted to get back into it.
