EroAdvertising is for many years one of the top adnetworks. Of course each network has their specialties. Exoclick could be better in geo A and Eroadvertising could be better in geo B. Of course there are way more (good) adnetworks out there, but I think it's quite unfair to say that Eroadvertsing is performing 3 times less, based on such less info. In my opinion Exoclick & Eroadvertising are both very good, but there can be differences in performance between the geos, devices, carrier etc.
