You do you, amethyst is great, it may crash here and there, but it's been better and this is to be expected from cutting edge technology.
Maybe plebstr will aim to be stable, then it also aims to be slow at introducing features making nostr boring IMO. In the future, when the hype is calm, then we can move on to stable clients.
If plebstr is just new, expect the experience to be bumpy and buggy.
