I bring this up because some people don't like the popular hardware wallets like Trezor, they have their eye on new hardware wallets coming up this days simply because they have better screen and good looks compared to the normal reputable hardware wallet that we know, if you are this type I still believe that reputation is everything but if you want to go with hardware wallets from new companies you need to make sure you are doing it right.
What wallet do you now consider as been reputable, you have only condemn but didn't provide solutions.
Open source wallet gives room to alot of things, security architecture measures and development, free access for people to modify and improve or make suggestions if there is any bug or recommendations, all these you can see it on a Trezor wallet but it doesn't make Trezor the best.
It's not like if you use Trezor wallet you can't have good security, you can actually have one of the best wallet to store your keys from the internet but the fact that you need to be connect to a functioning laptop, possibly connected to the internet makes it vulnerable. If not for the recent launched Safe 7 model of Trezor, you can't power on any of the previous models without usb cable but even with the recent relaase, you still need Bluetooth to be able to use the new model which breaks the purpose of airgap.
If you are going to use a cold wallet, if it has all the fancy features and it doesn't work like an airgap wallet, then there is tendency of it been vulnerable in one way or the other.
