No; the OBJ format does not support per-vertex colouring or per-vertex
texturing.

If your software of choice provides dedicated mesh2 output, then it is
certainly wise to stick to mesh2; the difference in speed is not that
impressive.

If on the other hand you would be using export to some other format
anyway, and convert to mesh2 from there without further processing, then
direct OBJ import is probably the way to go.
