Even if the Alps and the Carpathians are pretty similar (the mountains that the Transfagarasan road crosses are actually called "the Alps of Transylvania") I guess it would be kinda unfair to compare the two roads... first of all, the Austrian alpine road goes higher up in altitude (a definite plus in terms of driving complexity), secondly the Romanian road was more crowded with motorists (when I went there) and it has way more asphalt holes (notice I used the present tense - since I know for sure they did not fix it in the meantime).
Overall I'd just like to say that the Transfagarasan is definitely an experience that must not be missed.
