Being the initiator of this thread, I find it necessary to share my own feedback of P1 Cinturato Verde (made in turkey) since I finally bought it couple of months ago from Blue Area ISB.
I have driven in the city as well as on the motorway and I have to say they are pretty good to say the least. I can't really compare with other tyres since I haven't driven the same or similar car on any of the other tyres being discussed. However, P1 Cinturato's are comfortable (definitely soft), quite and have good grip as well. At least, I haven't come across a situation till now where I felt the car loosing grip because of the tyres and I can tell you that I don't drive very slow or calmly.
To sum it all up, I am quite satisfied and happy with the P1s. Just make sure you get fresh tyres, imported through proper channel and avoid the smuggled ones which are available in the market at a cheaper rate but you will find them hardened and relatively old (manufacture date).
The only thing remaining to be seen is how long they last and that is something only time will tell.
