So does auto, but the deal with adaptive mode and auto mode most times you can use apps in windows to adjust these settings.
I'm not sure about offset, it seems like it'd be the most reliable, but the problem you run into is that these settings will all overvolt.
If you're not using a high OC, any one of these modes would be great.
If you're trying to get high OCs near the threshold (Mine overvolted from the limit of 1.375 way up to 1.42 at one point), I recommend just sticking with manual.
