Controversial opinion

I find stephen kind of annoying. Especially from about book four up to about book 10, he is such a heavyhanded author insert. Sure POB writes him as scruffy, cantankerous, clumsy and susceptible to drugs, but overall it seems like there's a non stop list of things he's just the best at - doctor, surgeon, naturalist, linguist, duelist with sword and pistol, moral and political thinker, spy - i mean how many times do we hear sir joseph say "my god stephen what a coup!"? I do enjoy his character a lot of the time and think he gets more well rounded and better written later in the series, but i do find myself rolling my eyes more often than not when reading his exploits or hearing him lay out a moral tirade. It's not even that i disagree with the morality or politics, most of the time i don't, but often when stephen speaks it feels like o'brien proclaiming the Truth from his self insert who happens to be the coolest, cleverest, deadliest guy ever. Am i missing something? He is a really interesting character in many ways but i feel like he has this glaring flaw in his portrayal that i never see mentioned anywhere, and everyone seems to just talk about how hes the most fascinating and well written character in all of historical fiction
