Well if Stackage packages ⊂ Hackage packages, there is choice:
If you need the added benefits Stackage gives, "upgrade". Otherwise can stay with Hackage.

There's nothing stopping you from using Stackage in addition to Hackage. As an example, I used stack to create a new app-skeleton last night. One of the packages I wanted to use was the FFT package not available in Stackage. I just added it to the .cabal file, and ran "stack solver": % stack solver This command is not guaranteed to give you a perfect build plan It's possible that even with the changes generated below, you will still need to do some manual tweaking Asking cabal to calculate a build plan, please wait flags: carray: bytestringinbase: false extra-deps: - carray-0.1.5.2 - fft-0.1.8.1 - ix-shapable-0.1.0 Resulting in the following stack.yaml file: % cat stack.yaml flags: carray: bytestringinbase: false packages: - '.' extra-deps: - carray-0.1.5.2 - fft-0.1.8.1 - ix-shapable-0.1.0 resolver: nightly-2015-07-08 When building using "stack build", it automatically downloaded, configured and installed all my dependencies. No worrying about sandboxes (because stack handles this gracefully by default as far as I can tell) and no problems getting this simple skeleton up and running. Note that I used the nightly resolver simply because I wanted to use GHC 7.10 which I already had installed. There are multiple resolvers available (for GHC 7.8 and an LTS version with GHC 7.10 looks to arrive shortly after GHC 7.10.2 has been released: https://groups.google.com/forum/#!topic/stackage/Ux7ideofwIA) Bjørn Øivind
