Excluding knives, pistols, and launchers, you've got a total of 23 weapons to play around with in Call of Duty: Black Ops 7. That's a lot (though two less than Black Ops 6), so it's not always easy to know what the best guns are at any given moment if you're more meta-minded.
Of course, if you're going for all the Black Ops 7 Mastery Camos, then you'll be using all 30 of the launch weapons eventually, anyhow. Even so, it's a good idea to start with the meta weapons in the event that they get nerfed and become harder to progress. Or, better yet, the worst guns get a buff later down the line.
