WebAdjacency matrices are very good for dense graphs, and adjacency lists are good for sparse graphs. So it depends on what your graph looks like, but it also depends on whether you care more about running time or memory. If you represent your adjacency matrix as a hash table, you can get very good lookup times without using n^2 memory.
