(1) As you get closer to the VOR the needle gets twitchy, but it doesn't matter if you lose it - you're just about to pick up your next leg to your next navaid anyway, it doesn't matter if you miss directly overflying the VOR by a few hundred yards.
(2) As you get closer to the ILS the needle gets twitchy, but it does matter if you lose it - you're wanting to land on the runway so it does matter if you miss it by a few hundred yards.
