There's really no telling which one is more reliable since both cars are still very new to the market and how reliable it is depends on your luck. However, both cars seem to have good engine reliability from what I see. They're also good value for money but the Bezza is more fuel efficient whereas the Persona has a bit more safety features(also more expensive). You just have to figure out which one is more important to you(FC vs safety) as well as things like maintenance cost etc. have to factor in as well.

Depends what u looking for the new car. I'll sum up like this:

If u want Fuel save, more city drive and resale value, go for Bezza.

If u looking for everything else like Safety, comfort, big seat, stable highway drive, then go for Persona.

In short, maximize money saving = Bezza

Everything else = Persona

Let's take reliability aside since both is still new.
