Tilden is an all time great BobbyOne. He was instrumental in pushing tennis into new territory in many ways. I do know he was great, since there's so much evidence of how he was so dominated and innovated. I can't speak of him with the same knowledge I have of more recent players, partly due to how long ago he played. How they played well with the frames they did back then, I have no idea! There's no way to dismiss how much he accomplished so I understand your point.
