I find it hard to answer since i have not tried most of the cars and some is not on there, where is 406?
Of the peugeots i tried is a:
405 1.6 gasoline(My mums first pug) slow and steady, died to rust after a impressive 900.000+km on the same engine, great comfort
405 SRI (My mums 2nd pug) fun car great comfort
406 2.0 turbo upped to 216+bhp (My mums old 3rd pug lol) Insanely fun car, great handling aswell, great comfort, my mum totalled it after putting a "PersianDecorated"(no offence ment) BMW in its place. (did i mention my mum is 55? lol)
406 1.8 Ok car, good handling, abit boring when used to the 2.0 turbo
206 GTI Upped to 159,5bhp(my current car) awfull handling(before coilover kit), Not fun to drive(before coilover kit) , horrible comfort!(even with stock shocks)
, very noisy interior(before i spent 600+pounds on silentcoat).
As the most allround car compared to year aswell i would probably go for 405, though the 406 turbo was concentrated awesome, its smaller models seemed less nice to drive than i remember the 405 models.
