Individual Throttle Bodies vs Turbo

Each has its own advantages and disadvantages depending on the application it is used for.

ITB are great for the track(track as in a road course with corners, not a dragstrip). Entrance and exit corner speeds will be better with ITBs because of the high response and smoother power flow. The increase horsepower will get it around the track faster and the increase response helps in getting up to speed quicker for the next corner. Coupled with a good set of cams and upgraded lighter valvetrain, you can get more horsepower and a higher rpm limit. The disadvantage is that it is costly upgrade for the amount of horsepower but for the application it is used for, it is worth it. The Yaris is light and nimble so a setup like this for the track will be great. The main advantage of the Yaris on the track is its cornerspeed and ITBs will greatly improve it. With ITBs you get the reliability of a Naturally Aspirated motor without the worry of blowing something up, but just don't overrev it haha.

Turbo is good for those who want more power for the money. Turbo has its main advantage on the dragstrip where more horsepower means better times, but thats of course if you can get the power to the ground. More horsepower means faster car in a straightline. The problem with Turbo on the track(track with corners) is turbo LAG. Exit speeds are reduce because of the lag and lack of response. Entrance speed is also reduce because of lag and not being able to get up to speed quick enough. When the turbo does kick in, the sudden increase in power and torque will break its front tires loose creating understeer which will cause you to lift off the throttle and reduce even more speed. Since the car is FWD, breaking the front tires loose is bad since power delivery and steering are all controlled by the front tires. The smoother power flow of ITBs will keep the power to the ground.

Which you choose depends on the application you want to use it for because of the advantages and disadvantages of both, so choose wisely.
