We haven’t had a malfunctioning battery in ~40 000km of ebike use in our family. We have one that failed to charge due to age. The number of times we ran out of battery due to forgetting to charge can be counted on one hand. The number of flat tires is in the single digits - modern general use tires are really sturdy, especially if you combine them with sealant.
Must have been a high end bike because the ones I have used have had multiple punctures within a year and running out of battery in the middle of trip has happened several times which is not great if you live in a hilly area
The bosch drivetrain is pretty much bog standard on the german market and available on almost all price classes and Schwalbe Marathon/Big Apple tires are aren't exactly restricted to the higher price classes as well.
Now, if you're riding Mountainbike or Gravel tires, your tradeoffs are different - they sacrifice puncture resilience in favor of less weight.
The “high-end”-ness of a bike and the likelihood of punctures are completely orthogonal. You can get a low-end e-bike and just put decent tires on it. Since weight is less of an issue with e-bikes than acoustic bikes, it’s common for people to choose heavier tires like Schwalbe Pickups that offer very high puncture-resistance.
