I just got a new keystone hardware wallet, what should I do with my old ledger?

Should I keep it as a backup and just never plug it in, thus never getting updates?

Would it be reasonable to use the same seed phrase, or should I make a new wallet? I'm already happy with my chosen security method of my existing seed phrase and it would be kind of a pain to do it again.

Should I reuse the seed phrase and destroy the ledger?

And how is keystone in general? Any pros and cons I should be aware of? I haven't had any issues with my ledger, but I'm aware of people's concerns about the seed phrase recovery code. I'm not really sure if those concerns are a tangible risk or not, but I was hoping the keystone one might be better.
