Here are my thoughts:
[name_u]Max[/name_u]-I love this name. I like it as a nn, but also think that it stands on its own just fine. It’s smart, manly, a teeny bit quirky, simple & grows up well. The only downside is that it’s a bit popular, but it’s not trendy. It’s more on the classic side.
[name_u]James[/name_u]-This is a nice name. It’s a solid classic. [name_u]James[/name_u] sounds like a nice smart guy, w/a little bit of ruggedness. The only downside here is that it has a lot of nns. That could be a good thing if you like all of the nns. But, for example, I personally don’t care for [name_u]Jamie[/name_u] or [name_m]Jim[/name_m]/[name_m]Jimmy[/name_m] (but love [name_u]Jem[/name_u], go figure), so would be a little afraid to use this in case people call him that.
[name_m]Miles[/name_m]-This is okay. I don’t dislike it; it just doesn’t have the same charm as [name_u]Max[/name_u]. I meet a lot of new babies named this too.
[name_f]Hope[/name_f] this helps.
