Hmmm for the turks archers... normal archer is needed cause desert archer is limited to a few province ..(even though they are more useful in almost every way)

Although jannisary infantry is obvious the best of all the hybrids... they are a high age unit with a stiff req and can only be built in one province unless u mod or go through long pain of demolishing and rebuilding grand mosque...

Futuwaa and turcoman are both quiet useful.... futuwaa are like a ghazi with a bow... they are very powerful on the flank.. while turcoman aer surprisingly resistent in melee.... they can hold the line quiet well and let you flank... (unlike most other archer when something hit them their dead)... turcoman also gets a valor bonus province which means they are more effective than normal archers....

Jannisary archers however is useless unless u mod so u can built multiple academy easier..

Ottoman infantry are useful if u start a late era game but that's it.
