I wouldn't know anything about the surgery but unfortunately I hear m to f is always harder and the only thing you can do is train your vocals.
A very interesting topic! There are aspects of the transition that can be simpler and more complex.
If you take female hormones, the breast grows easily and the fat passes to the female type, the skin becomes a little softer, the hair becomes less. The voice will become a little higher, because the vocal cords have already become rough during sexual development. However, the shape of the face and the size of the limbs are poorly amenable to hormonal correction. In addition, it is easier to take female hormones - there are many creams with a high content of hormones, it is safe for the liver, as far as I know.
If you take male hormones, the size of the limbs easily increases, the hairiness increases, the fat of the male type. The face has rougher features, and the voice breaks. The problem is the need to remove the breast and internal organs, because otherwise oncology may develop. Taking testosterone is more difficult - there are no creams, intramuscular injections are usually used.
From an aesthetic point of view, to match the usual "female" figure, you need to make more efforts, and some are impossible (or little possible) without plastic surgery. But there are a lot of big women; the voice is not always a big problem.
