In the latest SIM tool, having NuGet local is perfect. Gone are the days of lib folders and trying to keep track of the proper Sitecore dlls version. One issue I found is that when I used the new dlls, all my intellisense went away.
All you need to do it set each Sitecore dlls to CopyLocal =
true in Visual Studio.
NOTE: You will have to exclude them from your package if you are using TDS.
