It's hard to say. If you were to have them both wind up and hit a bag and measure PSI or whatever, maybe it is Lemiuex, and he basically fights as if he's doing that at times. For as much as people say GGG is hittable, and he is, he doesn't sell out for single shots. He doesn't sacrifice everything to land with power, so even as he's stalking guys and throwing bombs his feet are still on point and he sees things coming. Lemieux on the other hand aims to get close and put his whole body into his hooks, and he pays a big price for this against guys who can box. I'm not sure I've ever seen him hurt a guy or land anything big without doing so, in that sense GGG is much more "heavy handed", and he has a variety of punches that will hurt you even if he doesn't get everything on them. I think I only watched the fight between the two of them once or twice, but did Lemiuex ever even land anything? I know it wasn't the question but it gets at what I'm saying. I'm not interested in a rematch between them whatsoever, it's basically a mismatch as GGG is so much better.
