For the power to weight ratio (HP per tonne, from Paul Tan's):
Bezza: 101 derived from 94 HP / 0.93 tonne
Persona: 88 derived from 107 HP / 1.21 tonne
a difference of about 12.9%, advantage Bezza
This is for a car without any passengers / driver / luggage. For real life, a car will carry a driver and 0 or more passengers and 0 or more luggage. Its this power to weight ratio that I am talking about. A typical scenario would be for me to bring my boys for jumaat prayers. The four of us would weight about 390kg. In this scenario, the real life and actual power to weight ratio would be:
Bezza: 71.2 derived from 94 HP / 1.32 tonne
Persona: 66.8 derived from 107 HP / 1.6 tonne
a difference of about 6.2%, still advantage Bezza but difference is reduced by half.
Theoretically, though I'm not a mathematician, you can fairly easily calculate the approximate additional weight of when the power to weight ratio of both cars is the same. But let me not bore you with such details. My point is that using the power to weight ratio as a selling point for Bezza may not entirely be an accurate point. A literally big family will find the power to weight ratio to not be that much when comparing Bezza to a persona.
Btw, I am no proton fanboy. I am in the market to buy the best value for money car as a 1st car for my children. My eldest son got his last year. Now with new models coming out, eyeing one for my 2nd son. Bezza advance is one of the candidate car for purchase. iriz and persona being the other 2 candidates.
Good thoughts
Both car has pro and cons, it's up to the users choice depends on his/her interest

No point for us to fight who is better
Btw, I was just thinking about this, when I look at the new persona, it seems like the bezza has more option on appearance mods, just imagine different kinds of body kits/spoilers that can be added bcos of the basic design of the car, but as for the new persona, it's like the car has enough details, i cant think of what rear bumper kit to be put at the new persona
