By comparison my RIE UL2 is 100x, no 1000x better in every single way. Same for my 15 degree duck down mummy.
Are sweaters better now than then?? I don't know, maybe. But seriously, get out of here with the general notion that 19** is within a hundred miles of good modern backpacking gear.
About boots, unless you are in snow, boots are scam. Period full stop with whatever expansive definition you want to use. Comfy $30 sneakers from Big 5 are great. I do have some trail running shoes I use personally that cost me about $100. I'm sure they had great options 100 years ago.
