This is obviously a personal preference issue, but I try to avoid the Cabal macros since they don't let my code run outside the context of Cabal. I often times like to have a test suite that I can just use with runhaskell, and (unless you can tell me otherwise) I can't run it anymore. Also, I think #if GHC7 ... #endif is more transparent than a check on template-haskell.
