My own take on d 3 cars u listed
Fiesta Hatch
+ Really fun to drive (gearbox, steering sharpness n chassis control)
+ Compact (if this matters to u)
+ most modern design (subjective though materials is decent)
+ sedan has a more practical boot but design is less ugh-hmm.
- its a bit smallish n claustrophobic inside (dark interior n narrow windows)
- questionable after sales service n resale if it bothers u (but wit d amount of Fiesta-s flying out d showroom, it might improve)

Forte 1.6SX
+ drives most surefooted of all (think a bit heavy n stable feel)
+ value to buy for gadgets got
+ sharp design (though d increasing amount of Fortes might wear tis down)
+ feels better put together with best meterials of d 3
- harshest ride due to low profile n bigger rubber
- rear is a bit tight n feels claustrophobic
- after sales n resale like Ford, but also might change coz quite a lot of Fortes on d road

Vios
+ Feels airiest of d 3 (probably due to glass area n lighter tones)
+ 1.5 engine feels light on its feet
+ should return d best fc of d 3 here
+ its a Toyota so relase value is definately there
- too damn plain vanila looking (subjective)
- cheapest n tackiest interior materials
- engine sound too harsh esp at highway drives
- s'how feel shortchanged from d 4-speed transmission (every1s moving to >=5-speed, CVT, DSG etc) although theres nothing wrong wit it

But most important of all is for u to test drive all of them n ask urself. No point getting wat ppl recommend but not happy deep inside.
