The stats of P2000 can be found in the game files at \Counter-Strike Global Offensive\csgo\scripts\weapon_hkp2000.txt
The stats of USP-S are not in the same folder: they are buried deep in \Counter-Strike Global Offensive\csgo\scripts\items\items_game.txt (If you're using a text editor with search functionality, look for "has silencer")
What's interesting is that the USP's is actually based on the p2000 in-game, and only a handful of its stats are actually changed. Here are changed "attributes" listed in the file (I added the comments). You can see that every "alt"-value is with the suppressor.
"has silencer" "1" <- not sure, some sort of a value for silenced weapons
"spread" "2.500000" <- Base spread (no suppressor)
"spread alt" "1.500000" <- Base spread (with suppressor)
"inaccuracy fire" "71.000000" <- inaccuracy added instantly after firing (non-suppr.)
"inaccuracy fire alt" "52.000000" <- inaccuracy added instantly after firing (suppr.)
"inaccuracy move" "13.870000" <- inaccuracy added while moving (both)
"recoil magnitude" "29" <- recoil magnitude (non-suppr.)
"recoil magnitude alt" "23" <- recoil magnitude (suppr.)
"tracer frequency" "1" <- turns on tracers for every shot on the unssuppr.
"tracer frequency alt" "0" <- disables tracers when suppressed
"primary clip size" "12" <- changes magazine size to 12.
So, how do these differ from the P2000's stats?
From P2k's file (formatted differently, stats picked from here and there):
Spread 2.00 <- higher than silenced usp, lower than unsilenced
InaccuracyFire 50.00 <- slightly lower than silenced, significantly lower than unsilenced
InaccuracyMove 13.00 <- lower than either
RecoilMagnitude 26 <- lower than non-suppressed, higher than suppressed
TracerFrequency 1 <- normal tracers
clip_size 13 <- higher magazine size.
Apparently the amount of ammo is stored somewhere else (which also explains the way P2000's reserve got nerfed with p250 for no reason)
So what do these differences mean in practice, then?
Spread in-game is calculated by adding together the right values. For example, the first shot while moving would be spread + inaccuracyStand.
I'm not sure how InaccuracyFire works, but given its high value, it likely just starts at the given value and goes down gradally afterwards.
-------------------------
Finally, to the point:
There is literally no point in using the USP unsilenced if these stats are anything to go by. Therefore we compare P2k and USP:
The USP has slightly better accuracy overall unless specified otherwise, as its base spread is winning by 0.50
The P2k has slightly better moving accuracy by 0.37 spread, as the USP's edge gets nullified by the P2k's 0.87 edge in InaccuracyMove.
The P2k could be a bit better for spamming due to its edge in InaccuracyFire, but just like in the prior stats, the difference is negligible.
The P2k has more ammo in both the mag and the reserve.
The USP has a tacticool suppressor and no tracers!
Comes down to preference, still.
