I loved Dekmantel Selectors at Tisno which ran last week at The Garden. The perfect setting, a friendly & very international crowd, and pleasantly capped at only 1500 capacity so there was plenty of room to move about and very few queues.
It was my first time in Croatia and I really enjoyed it, also taking in Hvar and Split during the two week trip.
HOWEVER, I don't think it can really be compared to Ibiza. The setting is equally beautiful but festivals aside, we didn't think much of the music played elsewhere. Hvar Town, which has been dubbed "the new Ibiza" felt more like how I imagine Marbella to look now - lots of young people from Essex and Liverpool, dolled up to the nines to listen to generic house whilst pouring champagne on themselves.
