I've had one really fantastic engineering manager (miraculously my first solely programming role, wish I was still there), and I have yet to have another good engineering manager. The degree to which time was spent improving the product under the good manager was phenomenally higher under the good manager than the others. Granted this seems to be rare but a good tech manager can deliver crazy outsized returns on the line developers and also make their days easier.
