The Bravery are pretty fun -- I Don't See No Ring on These Fingers is probably the best track on the album, but they're nowhere near the Kaiser Chiefs. Employment is great, start to finish.
This is kind of an odd comparison though anyway since the bands aren't even that similar. Now if you compared the Bravery to the Killers, then that'd be a fitting comparison. I like the Killers a lot, but boy are they boring as fuck live (as the Bravery have recently accused them of being in their little feud).
