My first bike was a CB400, sold it in 2021.
VTEC is fun but honestly the noise was the biggest impact. You can feel a bit of change in power, it starts to rev more quickly and freely, but it's not a dramatic difference. For example, if you hit VTEC mid corner it's not going to upset the bike. And then when you're running hard you get into VTEC quickly (~6k RPM) and stay there.
Here's a video of me riding it, I spend most the time above 6k rpm.
