Genius brother stayed loyal the entire time and ended up being a brilliant councillor/vassal (after I landed him and gave him a couple duchies). Ended up being an amazing king, living till his 60s, getting good events/traits boosting all stats over 10, conquering most of Hispania for Aquitaine. I thought crap, but tried to make the most of it. Almost right before I make a move to disinherit the older son (who is about 13 when second son is 12), I die of poor health. My good ruler had two sons, first born kind of mediocre/below average, second born was a genius and was developing very well. Ended up with Hispania though so it turned out fine). In my 867 'Capet' try to form France game (didn't work, got Aquitaine but couldn't press claim on West Francia/France for bad luck related reasons.

Primogeniture feels more "real" for role-playing a Western/Northern European character, and it leads to interesting situations.
