What's the best way to get to Niagara Falls from Chicago should I go through Detroit or Buffalo?

To restore access to the Niagara Falls Suspension Bridge, the Erie got the Suspension Bridge and Erie Junction Railroad chartered in 1868. The line opened in 1871, running from eastern Buffalo to Tonawanda and then alongside the New York Central Railroad's Buffalo and Niagara Falls Railroad to the bridge. The Erie International Railway, chartered 1872 and opened 1874, provided a branch to the International Bridge, and the Lockport and Buffalo Railway, chartered 1871 and opened 1879, provided a branch to Lockport.
