I bet all 10 will be exactly the same or very similar except maybe the race but still.
I'd take that bet even with fighter being among the most pathological case in the initial EA because it's very likely at least one of those ten went Eldritch Knight. In either sub-class I'm sure some would pick dual wield, some 2h, some defence for weapon styles.
For a better example of how the EA really isn't representative Warlock is a good example. In EA, Fiend patron, Agonising Blast and Repelling Blast, spells as Hex and Mist Step are really synergistic choices that are hard to beat. But that's largely a function of the options that are missing. Limiting them to Pact of Chain, and no level 5 doesn't let you build entropy tanking melee Warlocks, which don't benefit nearly as much from the Eldritch Blast buffing invocations. That's what I mean by latitude within the base classes in 5e which 3e just didn't do. Even then I'm onto my third Warlock (+3 Wylls) and have done different things with all three.
