[Solved] Choosing new shaders in Unity5 when upgrading from Unity4.6.3

I just upgraded from Unity4.6.3 to Unity5. The shaders have changed and I am confused about the process I need to take to convert my project to the new Unity version.
The old shaders have been moved to “Legacy Shaders”.
Should I continue using the Legacy Shaders or try to use shaders that are non-legacy?

For example: I was using the VertexLit shader which is now “Legacy Shaders → Vertex Lit”. Should I change this to “Mobile → VertexLit”? Or keep it “Legacy Shaders → VertexLit”. Or is the “Mobile” only should be used for games run on Mobile devices?
Thanks.

yes. the unity5 “standard” shaders give me much better results than the legacy shaders. i realize this now. i am replacing all legacy shaders with the new standard shaders
