There are many similarities between the two series like how the main character does not like the situation that they are in and try to escape. Also, all the girls try to get the main characters attention. In my opinion if you like one you are probably going to like the other.

Though Nagasarete Airantou takes place in the present time and Vandread takes place in the future, both series have a similar feel. In both, the genders struggle to live together and understand each other's feelings. The comic relief in both is also quite similar because of the awkwardness of the whole gender issue.

Animes are really similar. Guy comes along to strange world where are beautifull girls. Finds one, who's her partner and the other girls try to steal him from her. You can find ecchi, harem and little romance in both
Nagasarete Airantou is similar to ZnT, ZnT FnK and ZnT PnR - all 3 series of ZnT and I think if you like ZnT then you'll also like Nagasarete and if you like Nagasarete, you'll like ZnT.
