Almighty Mind!

Absolute Mentifery has the same potential as both but is more controlled. I think its next step could be Almighty Mind or Reality Mind.

I'll go with Almighty Mind

Reality Mind just seems... lonely to me, I guess. From your perspective, you would be the only real thing in existence. I mean, sure, by definition, loneliness would just be a figment of your imagination, but I still don't like it.

Meanwhile, Almighty Mind can literally do anything, including go beyond reality as a whole, without any of that 'everything is your imagination' baggage.

Both are just as overpowered as each other, but I’m gonna go with Almighty mind.
