I think the ride would not be on the list of compromises. It's pretty incredible across the usual rough old UK country roads, very impressive. The issues are going to come from whether you expect it to be an all round family car. If not, buy one before they are all gone! If you really are comparing the two cars:
Back seat space
Boot is pretty tiny
Rear visibility not great
The screens, dash, general ergonomics etc are a long way off the Golf
Main problem with it is you spend a lot of time grinning.
I got back in the Golf like it was a loved old arm chair, comfy, everything just right.... and so damn boring to drive in comparison! 
I very rarely arrange test drives- the last time I tested a car I didn't buy was an Impreza in 2002.
My slight obsession with the GRY got the better of me and I've just come back from a 30 minute test drive.
Realised within 5 minutes that it's a poor choice for a daily.
For me, the ride is too firm. Have to say I wasn't too impressed with the damping either, though I did drive some pretty crap roads and perhaps I was expecting too much.
Definitely agree about ergonomics- no comparison with the golf.
Driving dynamics? I've no idea! It's no coincidence that all the journos who are testing this car are doing their video reviews from fast open roads in Wales/ the Scottish highlands. On the roads I drove today- some fairly congested B roads in North Worcestershire- I didn't get close to getting a feel for this car's dynamic character. Just felt quick- and planted. And, strangely, a bit heavy.
The golf is more fun on these roads. Honestly.
