Who faced the tougher opposition?

There's a good argument Hopkins did, but he also lost.

Who'd they miss? Who should Hopkins have faced and didn't? Same for Floyd.

I would argue Floyd's best wins are Corrales and De La Hoya. I think?

I'm less impressed by Floyd's recent opponents, considering his contemporaries faced tougher opposition. For example, Cotto faced Pacquiao, Margarito, Trout and Martinez, and at least Pacquiao was in his prime, and Mayweather didn't face any of them.

Hopkins' recent opponents, Calzaghe, Dawson, Pascal, and Kovalev are probably better than any of Floyd's in that time period, although, once again, Hopkins lost.
