Iron Pipe: Is this an acceptable cut?

I'm fooling around with some of the work the plumber before me did on the waste stack, and came across a cut iron pipe end that looks pretty nasty.

I ended up doing all my cuts with a cut-off wheel, so everything came out flat and clean (2nd photo).

The cut I unearthed -- well, pic #1 speaks for itself. Is this typical of a pipe cutter on new no-hub CI? There's no way the neoprene sleeve was sitting flush on top of this. In fact, any fitting I place on top of this naturally wants to sit at a lean of 10 or 15°.

It's been installed for about a year, and has only seen light use connected to the only toilet in the house during construction. No evidence of leaks.

Should I leave it alone? I'm wondering what else I'm going to discover if I pull this section off to clean it up.

Snap cut pipe is typically a little rough. The Shielded Rubber couplings have a ridge that prevents the two pipes from touching.
It's fine.

If we had to put a "square" on the cutter every time we wanted to cut cast iron, we would never get anything done. And the cutter, by its nature, does make a ragged edge. Your pipe is fine.

I've been using an abrasion cut-off saw to cut my CI and I end up with very clean sharp edges. I've been chamfering the edges inside and out with a half-round file out of concern that the sharp edges might somehow work against the rubber coupling sleeve (particularly the ridge) and cause some problems. Am I being paranoid or is it a good idea to file the edges as I've been doing?

Also, a little off-topic... in some cases the shielding on the coupling gets a bit crunched on one side (say if the two sides are inadvertently tightened unevenly)... the result (when re-tightened evenly) is that there is sometimes a little bulge in the shielding. Is that acceptable or should any such shieldings be discarded? (I can supply a picture if needed.)

Thanks!

The only thing I would do is to make sure there isn't a lip on the INSIDE of the iron, the band bulge I wouldn't worry about unless it's extreme.

JUST BECAUSE YOU'RE PARANOID DOESN'T MEAN YOU'RE NOT BEING WATCHED! LOL
