Trezor, like Ledger, is a name synonymous with crypto cold wallet storage. Its Model T is the second generation of hardware wallets they have created. The Trezor Model T is very much like the Ledger, but it gives the user the ability to access third-party exchanges, like Changelly and Shapeshift, directly in its website interface.
The Model T utilizes a touch screen, which can be easier to use for beginners than the buttons the previous model used.

The deleted wallet, and crypto within it, can still be seen in Ledger Live, but the wallet will not be seen on the Ledger device itself.
This means that if you would like to send or receive to the wallet you have deleted, you may have to delete another wallet to make more room.
That said, the Ledger Nano S is still a fantastic wallet for those looking to store their cryptocurrency safely for a fair price. It is also quite easy to use with Ledger Live, making it an ideal product for a beginner looking for safe and simple storage for a handful of cryptocurrencies.
