I'd prefer more shorter towers spread out. The smaller they are the faster they fill up and new ones need to get built. As long as they are around 200 meters it feels pretty well the same at street level. Let's focus more on expanding the footprint of downtown by filling up Yonge to Jarvis with 50 storey buildings. More buildings is generally more impressive than fewer slightly taller ones. There is more streetscape to enjoy that way. Looking straight up is fun for some people but for most looking straight ahead is more enjoyable and more practical.
50 storey? I don't think there is a single 50 storey tower between Yonge and Jarvis.
