It (any resistance berry) is kinda useless if you are slower than the opponent. They hit you once on the switchin (or while you're already in, I guess) for less damage, then hit you again before you do something back.
That's why I wouldn't really consider outside of something that's able to increase its own speed with Dragon Dance, such as Salamence. Getting a Dragon Dance while they hit for less than 100% could be a big difference, especially if you can get 2 of them (1 as they switch to a counter, 2nd as they try to use Ice Beam or another Ice attack).
Otherwise, I wouldn't really use any of these. Even with Item Clause, there's usually better options.
