I like absolute/unlimited powers very much, but have nigh-complete arsenal, with powers and abilities that I like, would be very great and enough.

Cosmic Telekinesis sounds like a dream come true, for someone who wants to reach out for everything. I am among those 'someone'.

I'm fine with Plant Manipulation. Thanks anyway!

I will go with nigh complete arsenal with it have my favorite powers in there. It might have the best of the ones mentioned here as well.
