Of course it is slower, because it is actually using the lightning network, while on stacker.news only the internal db gets updated.
Stacker.news: click bolt -> update Database -> finished Nostr: Click zap -> fetch invoice via LNURL -> pay invoice from wallet -> wait for nip-57 note for confirmation ... there might be even more steps involved.
Point is, you can NEVER beat the UX of a centralized solution. This is a known trade-off. Centralized solutions work great, until they don't work at all (you get censored, blocked etc.)
That being said, i think the payment UX on nostr has still room for improvement and it probably will improve a bit over time, but it won't reach the UX you would experience in a centrally managed Payment solution IMO
Not necessarily, if it is from Alby -> Alby then it is essentially also just a db update. But the latency comes from several steps, that can take long even if no "real" LN payment happens:
  • Fetch LN invoice over HTTP
  • Dispatch invoice over websocket
  • invoice gets paid
  • Zap Nostr event gets published to relays
  • Zap Nostr event is received by your phone
