It's an ok deal, not necessarily a better buy. It depends on what the octo is. The swivel on the second is generally unnecessary except when you have a second bottle (pony or stage) and you have a specific hose configuration you want to use - otherwise it's a very minor convenience which adds another point where you could have a leak.
Also think carefully about the analog console, there are alternatives: you could buy a small SPG and have depth/compass on your wrists, which eliminates the bulk of the analog console and the streamlining issues (or you could get an air-integrated analog console computer, and eliminate the computer from your wrist etc - just make sure you consider these options and not just end up with something sub-optimal for you just because it's bundled)
