I find Revolution best
But its mainly what the player prefers, Lazy? Use revolution
Not Lazy? Use Manual
Sigh, pretty crap explanation.
Momentum - Your character pretty much does all it's own thing where you don't click anything.
Revolution uses your abilities for you, But doesn't use thresholds. It does however use ultimates so be careful.
Full manual has a higher DPS (Damage per second) And is pretty good for doing things quickly when you're only really concentrating on runescape.
You could also use Non eoc which gives you the old combat style and old interface too but i wouldn't recommend this for combat.
