It's quite a generous take on Alonso's lack of accomplishments at Ferrari to group him up with Schumacher. Neither Vettel nor Alonso has been able to do what Schumacher did. That's understandable, they're not Schumacher.
But to be fair, Schumacher spent more time at Ferrari than Vettel has so far before he won his first title - and he didn't have face down the most dominant team ever, either.
Let's wait and see what 2019 brings to the Scuderia.
It's not just absolute success, it's having a measure of the teammates and scoring above what could be expected given a certain car.
Vettel already twice had a car good enough for the title and he actually never put up a title challenge, being soundly defeated both times. Alonso brought up the fight to the last race in what was, especially in 2012, a car way down the pecking order.
After his years in cheating rocketships, Vettel was convincingly beaten by the drivers in same or lesser cars in 2014, 2017 and 2018. In 2016 he lost in qualifying. In 2011, in the one and only race where only a part of the cheating advantage that his car enjoyed was taken away (British GP), he was already unable to win.
After the 2009 Belgian GP, I predicted that Kimi will never again win there because he was so incredibly lucky since 2004 (2008 being an obvious exception) that it was impossible for this improbable chain of events to continue. The same for Vettel - he owed his titles to sheer luck as much as to unfair car advantage (because he has never been good enough to capitalize on it properly, unless it was so huge that anyone could have done so), so that I was sure that it had to end. He is a top 50 F1 driver but no more and that's probably already a stretch. Never in the history of F1 has there been a bigger gap between the statistical success and real quality. Just as Alonso said, one day Vettel got the car more like the rest of them and we saw that he couldn't do anything with it. That's why his four titles, in the light of his later career, are basically worthless.
