Hypothetical Situation Question

So.  Let's assume a powerful, whimsical being approaches you, and demands you make a choice.  It wants to turn you into an angel, faerie, imp, or pegasus.  Whichever you choose, you will get the equivalent powers of.
However, for the sake of making sure you have few responsibilities, are not overwhelmingly powerful, and build this life more as you like, you will be turned into the equivalent of a child for that race.  You may have your gender altered however you like as part of this change.
As an angel, you will be obligated, encouraged and able to do good, and similar applies for you as an imp.  If you become an imp, you may ascend to a demon, daemon, succubi, incubi or other such creature with species.
If you're a faerie, you get a home in a pocket dimension of your own, and in the faerie realm.  You may go by the "old ways", and do malicious things.  Or you may just do mischief or goodwill.  The only catch is that you must report to the faerie queen at the end of every day, or be harassed by older, other, more powerful fae for your "crime".
And if you're a pegasus, you get access to Equestria, and, although, you may be expected to learn to manipulate weather and do it, you will be otherwise without responsbility.

Which would/do you choose?  State your reason(s).
