Ledger Flex vs Ledger Nano and Trezor Safe

Hello everyone, I hope you’re well and bullish

I need your advice on hardware wallets for long term holding purposes, which is the best path to choose, go with the ledger flex, now that it comes with the recovery key which is a good addition or get a combination of 2 devices, ledger nano s/x and trezor safe 3/5, most likely these two or suggest me other good devices , I would really appreciate it. I’m no expert when it comes to hardware wallets as I never owned one but I think it would really be useful and I increase my holdings over the next couple of years.

Thank you!
