Obviously, there are certain superpowers that are pretty common, and what people think of when they think of superhero comics - flight, super strength, super speed, energy projection, telepathy, telekenesis, etc. But what about some other powers that are maybe not awe inspiring or redoubtable, but are ones that you think are really neat (and would perhaps love to have) nonetheless?
Here are some for me.

Cool underrated powers
Cypher's ability to basically automaticall learn any language. I would love to be able to speak any language! This also extended to computer languages for him, which would obiouslby be extremely useful.
Superman’s ability to speed read (at super-speed) & retain everything. My memory sucks, and I really admire someone that could remember everything he reads. Superman's can basically have the Libray of Congress in his head!  As an extension, Flash's ability to read at superspeed has allowed him to learn things (such as a foreign language) in minutes.
Taskmaster's abiltiy to master anything he sees. For instance, becoming an expert archer from watching Hawkeye shoot for a few minutes.


Interesting or unusual powers

Dazzler converting sound to light
Spider-Man's spider sense
Dr Mid-Nite only being able to see (unaided) in the dark
