Selecting HD Recorder AJA or Blackmagic

i record live weddings,events.i m really confused which recorder to use AJA KI PRO or Blackmagic Design HyperDeck Studio..things about this two recorders came to my knowledge is that AJA record proress 422 and Blackmagic Captures Uncompressed HD QuickTime Files. my concern is that i edit on FCP 7 and i m really willin not to spend on AJA but the footage of blackmagic , does it intergrates with FCP 7. setup can be sony HXRNX5U camera ,Switcher can be ATEM 1 M/E Production Switcher & confused between AJA ki pro or Blackmagic Hyper Deck.

NOTHING IS PERMANENT
