I've always thought that the equivalent of Albert Uderzo in the USA was Carl Barks. I'm not sure why, but the adventures Uncle Scrooge got up to remind me of the adventures Asterix got up to.
Duck comics are quite popular in Europe too and Carl Barks is honored, but I’d say he is not comparable to Uderzo / Goscinny. You could claim that Don Rosa is comparable though (looking at historical / cultural references, dedication to detail and effort that went into each panel). Can’t recommend „The Life and Times of Scrooge McDuck“ enough.
Europe produced huge amounts of Disney universe comics, which apparently there was not enough market for in USA. This happened in 12+ countries but oddly not UK.
There are 500+ (!) books in the series that have been coming out since 1950s, in A5 pocket format and with 250 comic pages. Most have been written in Italy the translated.
They are so European that I cannot even find an English wikipedia page for them but here's something in Danish: https://comicwiki.dk/wiki/Jumbobog
"Music Inspired by the Life and Times of Scrooge" is an album by Tuomas Holopainen, which I really enjoyed listening to. And yes, it's related to the comic series. Don Rosa provided the cover artwork for the album.
Having all Don Rosa comic books still in my shelf. Two of them with his autograph. Naturally all in Finnish, him and Barks being almost like national heroes in there.
I think the whole “went off the deep end pursuing a religious epiphany that required him to call women uncreative receptacles for male creative power” thing disqualifies Sim from being compared to Uderzo.
(And I say this as someone who leant a LOT about comics reading Cerberus.)
