Which DC games should I take?

[PortunusPelasergei]

I've been playing DC Ardennes, just a few small scenario and it was already a blast! can't wait for full Ardennes Campaign using both side (US/GER). I'm thinking of taking another DC games since I think I like this series besides SC series (which is broader in terms of scale). But between those 3 games, Warsaw to Paris, Case Blue, and Barbarossa are all interesting title, I'm thinking to take all of it but as usual, the budget is tight . So, my fellow wargamers, which one should I take?

Also, since I'm planning to buy a brand new gaming PC (which ofc will use Windows 11) does all previous DC games runs well? let me know!
