Both are con artists.


Rhialto is more of a bureaucrat. Every magician in the Dying Earth world is a tremendous asshole. He's the kind who attempts to loot from his fellow mages via legal (mis)interpretation and faux-democratic politicking. He differs from Cugel by operating on a higher power scale (being a mage,) but is equally as outmatched due to the extraplanar opponents he must navigate.
Vance's prose is beautiful. I decry needless verbosity of the Movieblob type. While Vance's prose may sometimes suggest use of a dictionary, his characters' intentions are always clear from context and easily inferred. Thus, he combines both extravagant and flowery language with surprisingly direct meaning.

Neither story is in first-person, but the third-person follows each character quite closely. Especially in the case of Cugel, where I do not believe it pulls focus from his viewpoint for even a second.
I also recently read and enjoyed Fools Errant, another picaresque fantasy story written by Jack Vance fanboy Matthew Hughes. It was excellent, although I then approached his Henghis Hapthorn stories and found them rather underwhelming. Jack Vance's Moon Moth was a good time. Emphyrio too. I know I have Lies of Locke Lamora around here somewhere... I tried reading Book of the New Sun and bounced off it. Aside from the duel, I derived very little enjoyment from the first book. Joe Abercrombie is sometimes suggested as a writer of picaresque-influenced fiction. Eh. Closer to Count of Monte Cristo really. Nicomo Cosca is about the only picaro in his tales.
I guess I should have figured I'd enjoy picaro stories, considering my long-standing love for outlaw fiction like Robin Hood and Water Margin.
