This all comes down to personal circumstances and preference! Some people may find that paying the extra £35/£40 is worth it, others won't. It all depends on how much you use the car, i.e everyday or just weekends. I personally only use mine at weekends so next summer i'm gona go for some Toyo R1R's or similar as i dont mind them only lasting 6000 miles ish as that's all i'll do over the summer period. Other people do way more and need a tyre that lasts longer.
It's good that everyone gives their opinions and findings on tyres (it helped me chose mine) but some points are irrelevant to me and will be to others.
Classic one for me is that some run R888's but they just arent suitable for everyone.
IMO everyone has a different + / £ ratio and its making the choice that suits you best, based on your circumstances like useage and budget.
