Owning a model T vs model A

[The Eclector]

I'm one of those rare gents who's wife loves cars. She's been going back an forth about a Model A versus a Model T. She likes an open car such as a roadster pickup or a phaeton touring car. I'm looking for some practical advice from an ownership standpoint. Specifically, what is the difference when it comes down to maintaining each and how would you rate the driving experience between an A and a T?
