You can't go wrong with the French. I have used them on every level. The only setting I would prefer someother is a Pan map at Sid. You just probably need an AA GA in that game.
If you mean literally AW, then they are not as good above Emperor, again you need an early GA on pan maps at DG or better. Lower or just going to go to war after you get set up they are great.
Really great at lower levels like AWM as you can avoid a GA, till you want it. You do not need Nationalism as you have the Musketeer and can wait for infantry.
You get the commerce for the extra gold to pay for units and you get Alpha to get the GLB. Industry to allow for fewer workers in the ealry game.
