Sure, ledger is easier to use, if that is what you want, but new Trezor or Keystone devices are ten times better as multi-coin signing devices.
Perhaps, but we also have to account for coin support. Ledger supports most alt and shitcoins out of all the hardware wallets. I have never looked into Keystone, but I doubt they support the same amount of alts as Ledger. I know that Trezor doesn't, plus the support for Trezor is different for each of their devices. One HW might support a certain altcoin while the remaining models don't. Ledger, sadly, has an advantage in this aspect.
BUT, that's where that question goes. - Is there proof that there are there packets of data that are sent from a Ledger Nano S+ to the internet?
The hardware wallet doesn't do the sending. The software, Ledger Live does. It retrieves the keys from the device, divides them into shards, encrypts them, and sends them two three custodial parties over Ledger Live.
Well, if follow this version, then here is the answer to how to avoid possible potential data leakage for ledger users - don't use software from this company. Or in other words, connect the HW device to third-party wallets, such as electrum (any other), for example, and not Ledger live.
You need Ledger Live during the initial setup. At that point, Ledger would have gotten enough privacy-related information about you from its software.
