StarMax 127 or Intes Micro M503

Is there any advantage, optically or otherwise, from one to the other?

The major differences between the two scopes are the f number and the size of the visual back.
The Starmax is f12.1 with a smaller secondary than the M503. This should help bring out some shading that might be harder to see visually. The smaller obstruction will also help *slightly* with splitting double stars because of the diffraction pattern. The Starmax is limited to 1.25 inch accessories because of the size of the visual back. However, this visual back also has a T-thread built-in.
The Ites has the advantage to using 2 inch SCT accessories, allowing wider FOV and focal reducers for photography. The slightly lower f number will help with faint extended objects slightly.
Both should work very well on planets and the moon as well as DSOs that can stand magnification (open clusters & globs).
If I had to do it all over again, I would still get the Starmax, as I like the mount package for starters.
Hope this helps,

But the shorter focal ratio PLUS the fact it can take long focal length 2" EPs means it can have larger exit pupils, which is the indicator of image brightness. The Intes also has better baffles.
But unlike Stephen, I would still buy my M503 if I could do it again. I am not a big fan of package deals. You are sure to get a mix of opinions here.
