Should I Switch to Coldcard And Sparrow Wallet?

Current Setup
I use the Trezor model one, together with the Trezor Suite to keep the most of my Sats. I operate it only on my Linux laptop (with my home WiFi), that in itself is rock-solid, regularly updated and has almost zero chance of containing a malware (not MS Windows crap).
On top of that, I use the Blockstream Green as a mobile only wallet, for small balance and lightning payments.
I know maintaining the security of the seed phrase and all is vital, but technology and tool wise, does the above set up make sense, and bulletproof enough?
Prospective Setup
I am asking primarily because recently I saw a youtube video that advised cold card with Sparrow wallet. The HWW is not cheap (about ~USD 200 depending on the model) and then, of course, setting up the whole thing, establishing my own safety protocol takes time and effort.
Is that switch really necessary, and does it provide any extra layer of security/resiliency that I am missing right now?

If you're comfortable with your setup it might be best to just leave it for now.
You can use Sparrow for testing multisig or a seed + passphrase.

I don't think you get a lot more out of this setup. If you want to upgrade your current setup you could do the following steps:
  1. Use an additional passhrase (if you don't already use one)
  2. Create a multisig wallet. There it could be useful to use multiple sources for keys.
Keep in mind that those steps complicate your setup and can also be a potential danger to loose your coins.

If you're interested in privacy, you could consider running your own node instead of connecting through Trezor Suite. When I started running my own node I switched to Sparrow and Coldcard to complete the set. Haven't looked back since and am very comfortable with that setup for cold storage. If you're running Linux, then I guess you are interested in privacy and sovereign computing to some degree, and running a node on your own server would be a good fit for this.

Yes, I would absolutely suggest moving to a ColdCard Q, Sparrow wallet, but not until AFTER you are running your own node.
That’s where privacy (and increased security) can begin.
Trezor has your xPub key and knows all of your addresses, that they all belong to the same wallet, and their balances. They might even sell that data to chain analysis companies.
ColdCard doesn’t know my xPub because I have never plugged my wallet into an internet connected device.

You can still use your current setup through Sparrow and don't need to change HWW. In fact, you can set up a watch only wallet of your current setup with Sparrow by importing the xpub if you're just curious about how the client works (no need to connect the Trezor). The main benefits with Sparrow over Trezor Suite is that you can use it with your own node/electrum server (as well as better ui/ux IMO). If later on you decide to use Sparrow as your main client, you can use the watch-only wallet to create transactions and it will ask you to sign with your Trezor.
