Glee manages to pack an insane number of songs into each episode, which means there will always be a few standouts along with the inevitable dud or two. We've narrowed the performances from “Born This Way” down to the very best and the not-so-great. After all, not every Glee cover can be a bestseller on iTunes!

Best Performance of the Night: “I Feel Pretty / Unpretty” by Rachel (Lea Michele) and Quinn (Dianna Agron)
After some so-so songs last week, Glee raises the bar this time around, as we love a slew of the numbers in “Born This Way.” And even though we haven’t exactly been on the mashup bandwagon in the past, this one blows us away and sets a new standard. Heck, those harmonies alone nearly have us tearing up. (What can we say? We’re lightweights.)

The TLC portion is emotional, but the girls’ performance even manages to lend poignancy to a typically lightweight trifle like “I Feel Pretty.” Come to think of it, this may be the best cover of “I Feel Pretty” that we’ve heard in a while. (Considering that its main competition is Jack Nicholson’s version in the movie Anger Management, that isn’t saying much).

Worst Performance of the Night: “I Gotta Be Me” by Finn (Cory Monteith)
It’s hard to hate on this song too much, since Mike (Harry Shum Jr.) teaching Finn some moves is cute. Trouble is, the quasi-duet puts more emphasis on the footwork than the musicality, and we just aren’t wowed. We like Finn to rock a little harder, so we’re not sure the swing era is perfectly suited to his strengths. And when Finn’s flailing arms make him look like he’s shooing away a tenacious fly, you sorta just want the poor guy to sit down and let Mike do his soft-shoe thing.
