Dawg, first of all, I don't think Wasabi or Samourai are good solutions. I don't think coinjoin is the path forward at all largely because of the reliance on a coordinator and is inferior, since you want to use that word, to other things that are being developed like teleports and fidelity bonds and payjoin and all sorts of stuff. Even channel factories have privacy enabling implications.

"Trezors announced working with Wasabi longer than a year ago" well I didn't know that because guess what? I don't fucking follow companies and their dealings on a day to day basis. For the most part I try to keep them out of my life. Its not a fucking lie to not know something.

I was able to find this guide to connect to your own node from trezor: https://blog.trezor.io/connecting-your-wallet-to-a-full-node-edf56693b545

I haven't gotten electrum server to work personally though. The BWT dependency Sparrow uses has been easier.

And you know what, since you're going off, I'm going off. Fuck trezor and their shitcoin enabling, key fob. Run the damn Bitcoin only firmware if you have it all: https://trezor.io/learn/a/bitcoin-only-firmware-on-trezor

Passport pretty legit, coldcard pretty legit (they been slipping adding NFC to their shit and supporting Bitcoin NFTs though), Krux pretty legit, do it yourself pretty legit, but whatever you do as a Bitcoiner, be skeptical of any corporate defending account.
