Okay, so all of the Victrix, Perry and OG 2nd Ed. guys have been based or rebased as the case may be for the earlier washer-based figures. There are six French battalions, of which five are 24-man, and one 36-man.
The British are currently at five battalions, four 24-man, and one 32-man - the Guards battalion. Thanks to another TMP buy, I'm waiting on the arrival of a pack of Old Glory (1st Ed.) British Light Infantry. These are planned to be painted as 71st Highland Light Infantry.
So, in the end there will be six infantry battalions each for the French and British. Enough to flesh out two or three brigades per side.
Next on the painting schedule are some Perry British RHA and Perry French Dragoons - the left overs from the ones I painted earlier for my buddy. I hope to play the next Black Powder game based upon the Battle of Salamanca. This battle had the British and French forces pretty evenly matched; the British victory earning Wellington the reputation of an offensive general as well.
As far as the OG 2nd Ed. French go, I'd say the 1815 (& likely the 1812) guys are a decent match for Perry French in both style, uniform and size. The Perry are a bit more robust, but not so bad to look out of place - possibly even in the same units. (ERRATA: The OG bayonets are a little thicker than both the Perry & Victrix ones.) The 1809 OG 2nd Ed. French are a little smaller - even compared to the 1815 guys. Mainly they are little shorter; however, if you add some height to their base, as I did with plasticard, they look okay in their own units. The Victrix French, as well as their Highlanders are taller and larger overall than both Perry and of course the OG guys. In fact, the Victrix French and Highlanders are larger than even their own British regular infantry sets. Anyway, they all are not so bad to look out of place on the table next to each other. Especially when the cannons roar and the smoke fills the air.
