PC:
One of my favorite open world action games I've ever played

Steam Deck(some of these apply to the pc version):

Pros:
-Portable JC3
-if you have played this game on controller in the past its a very familiar feel.
-Your getting the full game experience
-The PC port is the definitive way to play this game and the steam deck version is the second most definitive way
Cons:
-Performance is shaky(20-30 fps) in certain conditions on Low graphics especially on the games large island and in big military bases but can keep a solid 40 fps in most areas.
-The map is a little finicky and needs a patch
-Do not play this game with motion blur on, Especially on Steam Deck
-You need to be connected to the games online servers(DRM) once before entering the map

Conclusion: The game is really good but is in need of a steam deck patch/Definitive edition, also if you have a shakey/no internet connection I recommend buying the game and its DLC on steam and then playing a pirated version of the game with DLC's as it skirts past the online functionality(do actually buy it as its a really good game and Embracier will hopefully fund more Just Cause games or a patch to this game in the future,)
