I'm on the fence whether to buy a Trezor or a Ledger S. I know they are both good. BUT:

1. I recently heard that Trezor had some security vulnerability exposed (with its recovery seed, I believe). What happened there, and is this a danger for the future?

2. Once my device arrives, I want to test the recovery seed (pretend I lost my device, and use the recovery seed to recover my wallet). As I understand, if I do this with the Ledger, the seed and thus my device will be worthless afterwards; whereas with the Trezor this is possible without problems. Correct?

Any hints of knowledgeable people would make me a happy hodler!
