So far I've been using Rite Aid & haven't had any problems with them. I have a stash of Johnsons & Pigeon ones that I haven't used yet.

For cloth ones I have some Avent ones but I find if my nipples aren't completely dry when I put them on that they stick which can be painful. I also have two pairs of Mazalicious ones which are really great, they don't even feel like you're wearing them.
