The 1st since it has the 2nd under its applications. ED is just one part of the bigger whole that is AP.
Unrestricted Self Development also has Absolute Potential but... I'd say Absolute Potential because under it's "Also Called", it can be referred to as Ultipotence and "we" all know what Ultipotence was/is, basically Omnipotence but knowledge is needed to do what it's gotta do.
Absolute Potential, easily. With Absolute Potential, there is no limit on what you can learn and learn from, and no limit to how far or how fast you can develop your capabilities. You can literally learn a power from your own imagination or a work of fiction and it will work irl. You can even learn illogical or impossible things, as well as absolute powers and things like them, and do all of this instantly.
Unrestricted Self Development is... a lot more limited, ironically. The main difference is that Unrestricted Self Development actually takes time - you can't just instantly learn stuff, you have to take the time to do it. You also can't learn from things like your own imagination or fiction; it doesn't have Meta-Learning like Absolute Potential does. You likely can't learn how to do illogical or impossible things either. There's a reason it's not an absolute power and Absolute Potential is.
Absolute potential
@AzQth I didn't think you could learn absolute powers, fictional powers, or powers you can imagine instantly with Absolute Potential...underrated ability
