I'm not sure Vettel is better than Perez at this stage, but with the wind in his sails in his prime I'm sure he was better than Perez, especially as he was/is a significantly better qualifier and that matters for dominance at the top.
But 4 WDCs greatly flatters him. And frankly that is the case with any driver who had a luxury of chances to win, so Schumacher and Hamilton are also flattered in a sense. But the more I watch Vettel the more I come to the conclusion that he's probably not a top-ten driver ever, given the sort of gap I perceive in performance between him, Hamilton and Alonso, who were all contemporaries and rivals. Having such a deficit and being a distant third best of his era, in my eyes at least, makes it pretty tough for him to crack the top ten given there are many other greats and many other eras and periods which could make up such a list.
But anyway, I digress.
On recent form Vettel is the Spinmeister and at this point it's become a caricature, given how often it's happened over not just a few months, but several seasons. The last time he was consistently impressive was the first half of the 2017 season and that's a long time ago. Perez brings in a lot of money and he is a points hoover. I'd pair Vettel with Perez, but almost all of us assume that ain't happenin'.
Swap Perez with Vettel if that's the only option being considered? It would be nice to keep a world champion on the grid but, at least for me, not at Perez' expense at this stage, given the loyalty he has shown to the team and the general quality of his driving, not to mention the money he brings in.
I'm not sure why so many have such pity for him either for his situation at Ferrari and the chance initially that he could have been forced into, at least, a sabbatical. I'm not talking so much for this forum but the general reaction across many forums and reddit and the webz in general innit. He's lived a charmed existence, and he hasn't performed particularly well at Ferrari and Leclerc now shows more promise. It is what it is. Now with his reputation and clout he might be about to conspire with Papa Stroll to shove Perez right out of Racing Point/Aston Martin.
