Difference.

Nothing is better or worse from another. It is all the same, only different.

As a child, things may have seemed better, but there were negative aspects too. Things are different now, but no worse.

All people, we are all the same. Only different. You could say we're no better or worse, though, some seem on a higher lever of consciousness.

All planets, and dimensions, I assume are just as similar. They're a different experience, with different frequencies, but ultimately on the same radio dial.
