Ultimately it does not matter. You will still get the updates either way. With yakju build, your updates will come from Google.
With non-yakju builds, your updates will probably come from Samsung since non-yakju builds are region and/or carrier specific and thus are supported by Samsung.
From reading this great board, I have learned that this is nothing new. Previous Nexus's were also set up in such ways. Nexus with Google builds will get the updates faster since it is straight from Google. Other region/carrier specific Nexus's will also get updates, but at times, weeks later.
