No. You should move students around more imo.

I've worked with good and bad at both. Some of the most difficult problems when you have students who have had excellent teachers and then get dropped into the real world. If they don't learn themselves how to apply what they're learning (the other side of the coin of training) then they're often no better than an llm stuck in a loop, they know the textbook but don't know the gray areas...

Also professors and researchers are required to be able to communicate otherwise they're useless to the field. They need to better.

I'm not saying every lecturer will hold any interest in every lecture course. I've had the ones who are there lecturing core material to avoid the dept losing its accreditation and I've done electives where the professor is off the wall and spends half of the time going on about their research instead of the address material (fun but painful come exam time).
