[MCU] Which power is greater: Scarlet Witch's chaos magic or the reality stone by itself?

I figure it should be the reality stone but it seems fairly unstable with changes reverting when the user leaves the area and it's mentioned in Multiverse of Madness that Scarlet Witch could conquer or destroy everything.

As seen in Thor: The Dark World, the reality stone is capable of extinguishing all light in the entire universe if used at the right time and place by the right person, without any need for the other stones.

Its limitation comes from the fact that while it has absolute control over reality it has **zero** control over time, space, mind, power or soul - and thus the absolute power over reality is normally short-lived, localised, unable to affect people's minds or souls, and unable to generate power to act outside its vicinity. 

Meanwhile the Scarlet Witch has a balanced set of things she can influence including a lot of reality, a lot of mind, some space, some soul and a large chunk of power (especially once the darkhold gets involved). Her control over reality is not as absolute as the Reality Stone's, but because she can supply the other elements she's far more capable.
