Apple’s lead in silicon is probably not going to be as apparent until the next frontier in mobile computing, but that doesn’t mean it isn’t worth doing. The chips are more powerful, but launching individual web based apps isn’t really what differentiates them.
For now, the benefits are more future proofing and come from the longevity of the phone, being more usable over time, overall smoothness of operation, consistency, stability, etc.
Apple’s chips are clearly advancing faster than the current use case calls for, but you can’t just jump to where you need to be when that time comes.
