I guess that it is just what one is used to and for preference sake. Seems to have a larger use with the ultra lightweight rubber powered modelers.
Back in the 1960's and 1970's, I used Ambroid, Sigment, Testors, Duco, Comet, I think Pactra and a few others that escape my attention.
Latter times, being older and more patient, better time managing, resorted to the carpenter water based glues. Found that they work in situations even where I used to resort to Epoxy for like in bulkhead firewall ply, maybe except for the most demanding cases, or where the glue is unsuitable for. Plus, it is easier to clean off the hands.
But I thank the OP for posting this, bookmarked that website. I have a stash of rubber powered stick and tissue kits, may have a go at them later on. When I was younger, they were a joy to build.
