This is a real basic description but:

Performance mics are usually stuff like the Shure SM58. A dynamic mic that can take a lot of abuse (both physically on the road and in terms of loud noises as well). They're sometimes unidirectional to make them less subseptible to feedback.

Recording mics are usually condensor or ribbon mics. They're more sensitive and not able to take the shock from loud noises or getting banged around.
They're omnidirectional or have switchable pickup patterns.
They usually run on 48v Phantom power which means they either use a built in battery, or they're powered from the mixer.

If you could only get one of the two, it would depend on what it's main use would be for.
If you're in a band and playing live a lot, or want to record anything from vocals to loud kick drums or crash cymbals, go with the performance mic. (Dynamic Shure SM58 for instance)

If you're looking for a nice sounding mic that really makes vocals or acoustic guitar stand out and will be mainly using it in the studio, go with a recording mic. (Condenser, Rode NT-1 for instance)
