poland actually managed to do pretty decently, even counter attacking into germany, which was somewhat humiliating, they executed the polish general responsible for that. france should have done better, they were also backed by the uk and their tanks were superior to germany's, they just lacked modern tactics, radios, coordination and adhered to outdated methods and were overrun. france's military was actually very modern and quite good despite some weird equipment choices, something not often mentioned.
