Eurolines vs Ecolines?

So, for those of you traveling by bus all over the Europe, what coach organization did you like more – Eurolines (operating international routes to over 500 destinations, 25 countries, sells passes for unlimited travel between 40 main European cities) or Ecolines (proclamed as organization which gives you the tickets safe and fast)? Is Eurlines similar to Inter Rail or not?

I think it actually depends on what do you need to do – travel all over the Europe or just from one destination to another? Anyway, I recommend Eurolines, cause it’s a network of co-operating bus companies all over the Europe and I think it’s a bit more developed and reliable than Ecolines. Another good reason for Eurolines is cause they offer discount of 10-15% for tickets purchased on Internet, while Ecolines offer only 5%!
