the best way is a metal cutting bandsaw that has a large blade and moves slowly. Its safest however the cut will have visible blade marks. But I've used a 12" disc sander to clean up the ends nicely and that is also pretty safe.
then second best is a metal cutting saw with carbide blade that spins at a slower revolution than the standard chop saw. cut is smooth but not too many people own this type of saw.
a chop saw works well also for cutting with a cheap carbide blade. However be EXTREMELY CAREFUL TO CLAMP THE MATERIAL as its real easy for the blade to cause the material to kickout, which could drag a hand into the blade, and best case often will cause damage to the saw if the pipe gets trashed into the fence. (I've had it happen to me in an instant --- wham --- fortunately I still have my hand).
I'd go so far as to say if you have a chopsaw its imperative to make some sort of wooden fixture which will help you clamp the pipe. Clamp down to the table and also up against the fence. Again, something that helps you clamp to a round pipe is in order.
good luck and be safe.
