I know everyone rates him, but even so I still feel people underrate Mr Berry. Being so young, especially for a lock, and not a New Zealander, he's still crafting his reputation. Players have to sustain their international place for several years before they start being recognised as world-class, so Berry's age counts against him in that respect. But more important than his reputation are his performances, and IMO, when he's fit, his performances are consistently class, which puts him in that bracket of the top players of the moment.
On the other hand, Lawes and Attwood cycle through patches of form. What they offer is obvious, and they will put in MOTM performances here and there, but they don't offer the consistent quality that Berry does. So I don't see them in the same bracket as Berry. Given how many options we have, I would be keen to look for more, i.e. Itoje sooner rather than later. I'm also keen to see more of Kruis on the international level.
