Considering the fact that the Holy Roman Empire was comprised of thousands of minor factions which obviously would not fit into this game, I believe they are extremely easy in relation to their actual strategic position in history.
As for the rebellious generals, I typically try to simulate a real Regum Teutonicum or however you spell it, by not requesting any local duke or so forth leave their region, and only use their heirs, and members of my direct royal line.
The only time I utilize dukes/barons etc., is for crusades or in dire straits where the empire is on the hinge of destruction.
They are infinitely more fun if you set house rules, in my personal opinion.
I'm not particularly interested in the holy roman empire or germany after the classical age or before the renaissance period,
but the do have a rich and diverse roster to reflect their position on the crossroads of europe.
Overall, a top notch faction.
Although i'm still fond of my Kievan Rus and proxy Swedes (Danes.)
