It depends on the surgeon. Highly skilled surgeons can produce topresults. Look at Zlatans and Ramos' nosejobs for example. Subtility is the keyfactkor. I had a noserevision and the surgeon did a great job. It's probably the most difficult procedure aestethically, but highly skilled surgeons know how the underlying bone and cartillage should be in the ideal case. Natural result is key. A nose should never look fake.
With men, it's different. In most cases, they don't need a nosejob. The facial structure is way more important. A good, prominent masculine nose is good or at least not a problem in most cases. If it seems a problem, there's probably a lack of good bonestructure (jaw, chin or sometimes cheekbones). Only in rare cases the nose really is a problem.
With women, noses are more important. A straight slightly upturned nose is ideal. Noseflares should be max. 2/3rd of total length from profile, max. 2 millimeter visible from the front. With some women a sligthty convex nose isn't a problem. Whichnose is in most cases. 110 degree angle from profile is ideal (if I'm not mistaken).
With men, a slightly convex nose or straight nose from profile is ideal. I personally prefer a slightly convex nose due to additional masculinity. Nose should never be upturned with men. 90 degree angle from profile (if I'm not mistaken).
Bottomline is: good surgeons with great aestethic eye produce good results. Bad surgeons produce fake noses or fake Instagram model noses.
