The best use of Jihad vills for me is offensive towering - Roamn, Choson, Babs, Shang, Phoen. Perisa should also get jihad so vills can ran. Roman and Choson are best imho - rush the legions in, then Jihad-vills to tower.
Another occasion is mentioned by others - that is you can not wall and can not protect your vills. Jihad enable them fighting small raid parties or run as Forest Gump.
The 3rd reason is for fun.
Jiahd vills can take down small groups of archers (even EAs), but do not try to fight SC, War eles, or heavy infantry. Good to mess up with cats, and can also try to get small group of ballista/heles if you have nothing else.
From my observation, the jihad vills collecting food from farm next to TC/G slightly quicker than ordinary vills. Wood collection affects over the distance but you can always build pits closer - I do it even without jihad.
