I'm not very familiar with 'masou gakuen hxh' specifically. But generally, for anime similar in genre, you could check out 'Sword Art Online'. It has a similar theme of a unique school - like setting within a virtual world. Another one could be 'Log Horizon' which also involves characters in a game - like world and their adventures.
If we consider the elements of a school and some sort of special power or situation in 'masou gakuen hxh', then 'A Certain Magical Index' could be a good choice. It's set in a world where there are espers and magicians in a school environment. There are lots of action - packed scenes and complex storylines that might appeal to those who like 'masou gakuen hxh'.
