I would disagree on a few counts:
1) I think your donor does not look that dense. I can see a lot of scalp and your hair is not that short.
2) I am not sure you would benefit that much from hair transplant. You have a LOT of hair on top, and given that you say you are stable on meds and that you are only 29 I would reconsider hair transplant. If you eventually go for hair transplant, save your grafts for later on when you may really need them.
3) If you get hair transplant you may have a long run for a short slide. Given the appearance of your donor and the potential for shock loss in borderline hairs on top (and in the back and sides) you may not get as much out of hair transplant as you hope.
Overall, if I were you I would hold off and push on with meds.
