Nice cars, both of them. I have to be hoenst and say that I the the looks of that ST more though, great looking car. My mate had an ST. After he got that I felt the need to get behind the wheel of soemthing faster than what I was currently driving. I can't say for definate, but I'm pretty sure your Scoob will handle power-upgrades better than your ST. You will find a lot less torque-steer and wheel spin if any, as you'd have to be really givin' it some to do that.
Welcome along! By the way, what mods did you need to get your ST up to 300BHP?
