Pirelli are making the tyres teams are asking them for. Teams asked for tyres with larger window and more deg and there you have it. There's no way you can say bridgestones or michelins would be better options because Pirelli is competing with themselves and doing a decent job in making races more entertaining.
The way I read BigChrome's post was that if you had a choice - no other considerations relevant, disregarding the reasons behind the tyre characteristics - between the last generation of Bridgestones and the current Pirellis - you would choose the Bridgestones. Which seems logical to me, you either get a tire that is potentially a second slower in peak performance (total guess!) but for which degradation is way, way smaller.
But it is clearly the case that the teams asked for a wider operating window (or at least the teams that had trouble hitting that window last year!), and that someone was asking for more deg (whether that be the fans or the teams I'm not sure).
Overall the tyre degradation is currently so huge, I don't know if the teams will even have enough tyres to finish races next year within the two hour time limit, if things don't improve! (Possibly hyperbole I know). It as funny, as I'm a Mac fan I was looking at Mac times yesterday and thinking the tyre degradation was terrible, got really nervouce. Then I compared with the other teams and saw it seemed quite favourable. Just amazing degradation seen yesterday.
But in honesty I think the teams will learn how to manage this, how to wrap the tyres in cotton wool and drastically improve the degradation. Just as they managed to do for the last two years.
