go for roman governor and print praetorians.
I would say play a roman king/duke if you aim for defensive playstyle and take a 9 cropper capital 
i would say play a teuton paladin anvil
highly suggest role: governor or duke
but i suggest to become governor or duke
clubs are cheap and very good for robber hideouts and robber camps
clubs can clear the robber via siege
and paladins clear the resource very fast
clubs/paladin are also good in raiding so you can gain much more efficiency with them than other tribes
if you are offline your vilage can be well defended just ask some gauls to share you their phalanx without worrying of getting wiped
you can also spam scouts while building your paladin anvil
play governor or duke it will give you good income, than playing king since its is a gamble
if your kingdom is not very lively then your resource income will not be as good as governors
if you ever choose gaul
here are some disadvantages as governor gaul if you are aiming for hard anti-infantry (druidriders)
barracks: you can only train swordsman for clearing robbers
stables: druidrider is the best anti-infantry because its the fastest and the def scaling against infantry is very nice, i can say better than praetorians in speed and but not in upkeep
swordsman alone are not very efficient in clearing robbers so you may not gain a lot with it
i want to play and test a full anti-infantry def style in next test server
but i am not sure what tribe offers the best in this forte
If you want to go for infantry defense the romans would be the first choice to come to mind, because of their praetorians. They are the most cost effective infantry defense both by cost and by crop efficiency. In terms of defence per buildtime the druidrider is the best followed by the paladin and the phalanx. The praetorian is 4th in this regard.
i am planning to style my account as 1 anti-infantry anvil city and the rest feeders
If you really want to go for a single def-village I would say gauls are the best, since you can produce phalanx and druids for a ridiculous amount of infantry defense per buildtime compared to both a roman going praetorians (cav doesnt really make sense here) and teutons (spears and paladins).
Typically a def-account produces troops in many villages and build time is not that important compared to resource efficiency.
Some other thoughts:
Another advantage of romans would be their ability to build two buildings at a time and their excellent late game scouts.
The teutons advantages for defense is their excellent cavalry defense with spears and their scouts cosuming only one crop. They are typically considered the weakest def-tribe, with their def clearly geared towards anti-cavalry.
Gauls have a really easy early game, the phalanx as am extremely powerful all-purpose defense and druids as fast infantry defense. They are typically considered the strongest def-tribe.
i can choose to play king/duke or governor depends on the best suggestion
I dont have experience as a king or duke, so all of my advice comes from a governors point of view.
If you are not sure what role to pick, I would suggest to go as governor.

While i agree with your advice i would say it is much easier to play def as a king or duke due to the extra resource income
