safety, comfort, maintenance, all saga wins.

safety - proton handling much better than bezza. better handling = less likely to lose control, less likely to get into accident
comfort - both also meh, but saga is less wobbly. beeza is tall, small wheels, so u imagine the ride la
maintenance - both parts also cheap, but i'll be willing to bet saga parts will be cheaper & more abundant in the future

FC & acceleration - both also hav similar FC, & acceleration is meh. but u cant trust paper spec. all perodua has the same problem, where after u put som weight in it (driver, passenger), FC goes down the drain.

conclusion:
if u love your family, get any car but perodua. perodua cars r notoriously horrible in handling & safety.
that's y u always see perdorua get into accident, & often fatal accident.
there is a reason y perodua car is usually about ~100kg lighter than their counterpart.
cuz use cheap ass tin milo.

bezza handling horrible.
meaning u're far more likely to get into accident at the first place.
also, bezza very vulnerable to crosswind.

i sit my relative bezza 1.0A, 3 passenger + 1 driver, the car feels damn underpowered.

actually all small CC engine also has this common problem.
the FC only good if no weight.
once add som weight, the FC even more horrible than higher CC engine.
