Honda CBF125 OR HONDA CBR125

Just did my CBT and thinking of getting a Honda CB125F, but people around me are saying it's too slow and I should go for the CB125R. Not sure if I should prioritize comfort or speed. I'll mostly be using it in the city and rarely taking it outside city. My main use will be getting to school, which is about a 30-minute ride. I love bikes, so any advice would be appreciated!
