I think everyone agrees Vakif is way better at preparing matches especially at knockout stages, but Ecz isn’t really a “clear level below” the other big 2 in TL. Ecz actually ranks above Vakif in both last season and this regular season in TL.
ecza won literally nothing of importance in the past decade, apart from a WCC against the weakest field ever. regular season doesn't mean anything, they're forever stuck at number 2-3 while vakif and fener are taking turns winning titles.
