2 version of windows buildbot, anyone noticed differences ?

For a while now there are 2 versions of the experimental buildbot version targeted to windows platform.
I’m curious one is builded in the ‘old’ way the other one is build using latest visual studio 2015.

has anyone noticed a difference, in between the 2 versions ?.
i just wonder why the hassle personally i always use latest visual studio products and now that vs2015 is free to install to develop blende, it makes perhaps sense to make the step to go to vs2015 ?.

Is this really Blender related or just about Windows? Seems like it would be more suited to Support / Other Software or Misc / Off Topic.

I haven’t noticed much difference myself. I will also note that the developers are thinking of making the VS2015 builds the official ones and dropping VS2013 altogether (so if there’s an issue specific to the new compiler, now is the time to report it).
