Could John be the best Spartan at

Using Covenant/Forerunner Weapons and/or fighting Forerunner constructs?

In the lore (the books) Spartans usually stick with human firearms and very rarely resort to using recovered alien weapons at least for regular operations.

But we know from the games that John has fought in multiple campaigns deep in hostile territory with minimal access to friendly support and logistics for resupply. So it seems likely that he's gained more experience using alien weapons and equipment relative to other Spartans.

Another thing is that he's also had to fight many Sentinels and Prometheans alone. In the books even other S2s need to put in a fair bit of effort when fighting Aggressor Sentinels and in a group no less.

Of course there's going to be a disconnect between gameplay and lore. But with what must minimally be canon from the games, would it be fair to say that, the Master Chief is the best or most experienced Spartan at these 2 things?
