That will result in a cliff-edge policer (i.e., as soon as a device goes
over its limits it will see every packet get dropped). This doesn't
interact too well with the burstiness of TCP, so you'll likely get
erratic behaviour of the traffic if you do that. Doing the same thing
with HTB means the router will queue+shape each class (and with FQ-CoDel
on the leaves, you'll get a nice AQM behaviour as well), so that will be
smoother and less prone to bloat :)
