Difficulty and AI Bonus Settings

[Wisdom]

Ive seen some talk about the AI diffuculty setting and how it should be played on high if you want a decent challenge. But what about the AI bonus?

Do most of you SE4 gurus out there play with the AI bonus on high, or does that make the game virtually impossible to win without alot of luck the save/reload twink. If so, how do the games go?

I mean does the AI bonus on high give you a good challenge or make the game ludicruously hard?
