Extensions, mostly. You have to be real careful which extensions you install because extensions run at the window level (mostly) rather than the container level and see across/through containers.
Also things like auto-fill (including password suggestions); if you like that being very specific to context, then you'd want different profiles rather than containers.
I've found I've been using a mixture of profiles and containers, myself, to balance ease of access (containers are fast to launch and can auto-launch per specific sites) versus better extension control and auto-fill/etc separation.
(ETA: As for finger-printing, both containers and profiles are equal on the most common finger-printing: cookies and localStorage. Neither protects you well from IP Address tracking, which is a growing concern, but not the approach of at least the big players like Google or Facebook, yet.)
