I'd say it depends on the piece. Storm Beast has open sockets that don't bother me, but then on other sets that do have it, it's really annoying. Then there's the more common ball-joints. On Toxic Reapa it doesn't bother me, but it does with other sets. Honestly I can only specify with ones that don't bother me because they are more peaceful and easy to cope with. If the socket/joint isn't that gaping or presence-declaring, then it's not too bad.
