I'm right there with you. I prefer collected editions for rereading instead of having to pull out comics from plastic sleeves and repeating for the rest. It is much more convenient to take a book off of a shelf and get right into a story. And that's awesome. The series had some really great covers.
There are 2 very distinct & different smells when it comes to older (25+yo) newsprint comics. There are the acrid, strong vinegar, acetate smelling comics. A very negative smell, imo because it indicates the decaying process has advanced to the point where acids are starting to separate and break down the newsprint on the molecular level. Interestingly, the same smell applies to older kodak film prints (pre-Estar based). Then there's the warm, slightly cooked, pulpy, print smell which I love that indicates a properly neutral pH mixed newsprint batch. It's a smell I got used to whenever I bought old back issues as a kid in the 80s. I knew of an archivist who lamented the loss of this at his local library when everything was converted to digital files (even the microfiche!) and even the old newspapers were treated with a neutral stabilizing agent that basically nixed the smell forever. If you are sniffing your trades & hardcovers, I think you are mostly smelling ink and fixative.
I guess you can say I'm something of a paper smell connoisseur.
Look at you, Banky! Here to burst our old-paper-sniffin' bubble.
Damn.
