Why not? I compare shows all the time to say “Oh you liked anime A? I think you’ll like anime B too”. Comparing pacing is fine and true in this case.
Key magic is usually hidden until late in the route (I know there are exceptions). Since this isn’t using route formats I’d assume if it is there it wouldn’t be actually revealed until episode 10 a the earliest. Even then I’m not sure that’s a bad thing, did planetarian have any real Key magic?
