Would I look good as a Ph.D. applicant if abandon one graduate program and then pass from another program?
Normally, yes, but there may be possibilities with a "sister" institution running the same course or similar course with the matching courses / modules where you could then move - of course this has to be accepted by both institutions.

Moving to a completely separate institution will normally mean a new course and the parts you have completed may go towards full or partial credit for the equivalent courses or modules. 

This would normally be evaluated on a case by case basis by the Dean / admissions officer or equivalent.

It is also very much dependent of which country or countries you are dealing with...
