I think classic overpasses are looking much better. Just my opinion. But the new J-12 will be very popular for sure, because you can put Plakids in it (of course, you don't get any with J-12!), and I bet kids (of all ages) would like that feature! 
Also, new J-12 overpass will look good with new J-11 Station.
