The bluecoats are French faring better in hand to hand and having extemely good cannoneers.
The redcoats are British faring better in accuracy (They were adapt soldiers and had the best line infantry any nation could offer) and having amazing cavalry.
My best bet would be to say that the british would win in a straight out line battle but if the french were using guerilla tactics then id say they would have the superior chances although if you use cavalry infantry hussars grenadiers and all that sort youll have to think on it for a while ok.
