This discussion here reminds me of PC customers buying behavior in the 90ies. What's better AMD or Intel? ... Nowadays other features are key: What's the weight of this device? How thick is it even? Apple has changed the way we look at these things today.
Convenience also matters in hosting a lot. How much time do i have to spend to have my app up and running? Do i really want to set up and maintain everything myself? How good is the support? Do i want just bare metal computing resources or a solution provider with an eco system?
What matters the fastest server ever, when the queries are slow? The performance of any app/website relies heavily on the engineering skills of the developers. See caching, see i/o load, see frontend technolgies, see #perfmatters.
