Best EU Realm for levelling? A few i've tried have been kind of dead

Been lured back to the glory of Classic levelling, and while i've been having some fun - grouping up has been a bit patchy, if not entirely absent.Levellin takes a while and I want to commit to a realm, but it's so hard to get a judge on a realm until you're past the starting zones.I'm going to chalk it up to no XP buff, most people maxxed and not many people running alts.I've tried Giantstalker and Earthshaker which are seemingly the most populated but even then it's felt a bit empty.
