The Sage code style is that methods are preferred over properties if in doubt. And even in plain Python I would really recommend to only use properties for static accessors. If you need to make a computation, use a method. This makes it clear to the user that there is a computation involved, even if it is just enumerating the possible representations for future use.
It might be a minor inconvenience to have to write sage: A=MyFavouriteAlgebra() sage. A.representations() sage: _.<tab> but its much more annoying to have A.representations.<tab> hang for a long time and then potentially raise an out of memory error etc. Also your UI might automatically collect tab completions before you even press tab.
