Why obviously Lithuanian? I also think that the only difficult aspect of Hungarian is the vocabulary. Besides that, I think Hungarian is pleasantly refreshing to grasp.
Lithuanian has a rather complex noun morphology, probably more complicated than the east slavic one (Ukrainian, Russian, etc.). The first grammatical "strangeness" of Hungarian, from my point of view, is that this language is agglutinative (a typological characteristic that doesn't belong not only to my native language but also to my scholastic background: I have experienced fusional languages such as Latin and ancient Greek but I didn't experience agglutinative languages). Besides Hungarian has not only a vocabulary that is difficult to get (being a non-indoeuropean language) but also its phonetics sounds completely alien to me. For example, the Finnish grammar is not easy at all and Finnish isn't an indoeuropean language too, but I don't find the Finnish sounds as complicated as the Hungarian ones: on the contrary I should be able to pronunce correctly a lot of Finnish words without too much exercise... with Hungarian it should be not that easy...
By the way I have never tried to study the languages I mentioned as the most difficult to learn, so you can convince me that Finnish, Estonian or Russian should be more complicated to me. I can say without any doubt the European languageS that are the most difficult to learn (from the point of view of an Italian speaker) but I can't say without any doubt which one of these is the number 1 as regards its complexity, also because it's not your native language to choose here, but your personal mental structure.
