Same vibe re Synthony for me.  Sound was ok at times, but lacking a bit at others.
Really wanted to get access to the mixing desk thoughts as at times during the actual Synthony set the orchestra was mixed way too low.
Synthony set was good. At times stunning, and at others felt a bit christmas in the park singalong performer.  Liked the two or so full orchestral sections as they sounded epic up loud and with a beat added.

We were in GA as all other zones are R18+ and I was there with my 16year old daughter.  
We got right towards the front of the GA standing area, but that got progressively worse as the night went on.
Being a festival you've got people drinking all day and culminating in a mess at the end, plus the usual festival drugs floating all around.
Was up front to get a view but fell back a bit later to avoid the crush and madness, and that actually afforded a better view too.
The bank would have been fine for a view but didn't have the same dancing vibes.

Kora seemed well out of place.  Vibe suddenly turn metalish and given the event and surround dj focus that didn't land well.
Saw a lot of people use that as a toilet/meal break.

Lots of clean toilets, good food, weather held off for the most part.
I liked it, probably would have enjoyed it more if sounded a bit better, and less idiots but hey that's NZ these days.
Good public transport and organisation, though the bus dumped us all on the outskirts of the CBD (just past spark arena) which everyone onboard felt surprised about.  That was an odd decision.

I'd give a 7/10.  Would return but not until can gain access to a better zone, so that's two years until youngest is old enough now.
