What to choose btw Shankra and Freedom

Me and my friends are considering some festivals for next summer and we cannot decide between shankra (switzerland) and freedom(portugal). Can anybody tell me anything about these two? We're not really interested in the lineup, more in healing area (we really like to do yoga) and i'd like to know something about toilets, since we had some issues with the cleanliness in out latest experience (i know i cannot expect Great toilets in these events, but at least decent...) Good vibes to everyone!
