It may be better to buy from other companies that offer really reliable devices and don't try to fool their customers with dubious collaborations (Trezor) and recovery functions (Ledger).
What do you mean by "dubious collaborations" is this what you are refer for
Trezor and Wasabi Collaboration Enhances Bitcoin Privacy with CoinJoin Feature?
It is related to privacy and not the security of your bitcoins.
Security is in ensuring that the private key is generated in a way that does not and will not connect to the Internet or that it is shared in one way or another with third parties, something that has not happened in Trezor.
In terms of privacy, if we take electrum wallet as an example, it is bad for privacy, as some electrum servers are managed by Chainalysis.
Chainalysis is the same company that does blockchain analysis with wasabiwallet and they're both trying to make privacy with CoinJoin questionable.
“The downside to this design is that when the user wallet connects to the network, a variety of information is revealed - the user’s IP address, the full set of addresses in the wallet (used and unused) and the version of the wallet software,” according to the slide deck. “Chainalysis runs a series of nodes on the Bitcoin network ... and if a user connects to one of our nodes, we receive the above information.”
Unless you're running a full node through Tor, relying on third parties, including electrum wallet, gives you questionable privacy.
