For broadcast and film, the industry standard is Avid with Premiere in second. Avid's educational price is $295, just under FCPX at $299.
You should learn Avid, Premiere and FCPX. This will make you well rounded and able to work in any post-production environment, since different programs are used.
FCPX will be easy to pick up. Avid and Premiere might take a little time but the larger post houses use those (broadcast and film). So it is best to know all of them.
Editing is the same no matter what program you use, it's not about the software. The only difference comes in with workflow, where it will be shown (matching back to film for theatrical release, DVDs, Bluray, internet, etc.), how many editors are working on one project, etc. An award winning film can be edited on any of those NLEs. Some NLEs are just better for certain jobs than others.
