I'm not a fan of watching the Captain stumble through the before takeoff checklist/line-up checks while I taxi from the right seat. And don't get me started on the after landing flow.
I'd rather just give him back control of the airplane and take care of all those things, thank you very much. Lest we get to the runway without TA/RA, or get to the stand with the weather radar still on.
While i'm not very passionate about the whole FO taxi thing, if the above is the case for more than the first two or three weeks it shows clearly incompetence on the captains in question. Give them a re-training session, if they dont get it and they still miss steps after that, show them the door, the lower seniority guys will enjoy that a lot
