I have the 2012 Choice, all around they are pretty solid.
I do have a few issues with them though - First is that the toe strap likes to move around no matter what I do or how tight it is (only for my rear foot). They do have the cups at the top but it doesn't seem to help much.
They are pretty responsive from what I can tell but a bit on the heavy side.
I have had the locks on the highback come off a couple of times causing my foot to release mid riding.
Over time the quick release on the heel/ankle area starts to seize up and needs a bit of a coaxing to open (not much though). Pretty much just picking out anything I can at this point.
Everything else is still in good condition - the colour on the toe straps wears away pretty fast though.
These are by far easier to get in/out of compared with flows.
As for going in the park - I think there are much better alternatives tbh. The others here will be able to guide you better with this.
