Well, I have a Blockstream Jade, but just like you, I don’t like the fact that Jade doesn’t have a secure element.
Therefore I would only recommend to use the Jade in a multivendor multisig. Not singelsig.

Have you seen the Portal? It's another Bitcoin-only wallet/signer that's made for mobile devices. It's powered entirely by the NFC connection, which is pretty novel. It's also reasonably priced, currently selling for $95. I don't know if it's got a secure element chip, but I joined the official telegram channel and asked about it. Hopeful they get back to me in the next day or two. If it does have the chip, it will have ticked all my boxes, and could be the device I choose.
The Portal NFC-only signing device is great, but it’s very new and therefore it’s hardware and firmware isn’t battle-tested.
What are your opinions about the Coldcard Q from nostr:npub12ctjk5lhxp6sks8x83gpk9sx3hvk5fz70uz4ze6uplkfs9lwjmsq2rc5ky and Passport from nostr:npub1s0vtkgej33n7ec4d7ycxmwt78up8hpfa30d0yfksrshq7t82mchqynpq6j?
I really like the Coinkite wallets, both the Mk4 and the Q. I think Coinkite has been very thoughtful in their designs, and have created hardware that's solid, reliable, and ready to manage the funds of the biggest whales. My only gripe is with the cost. I'd like to see them priced about 15-20% less. But I don't know their manufacturing cost, or their profit margin so I'm just judging from my consumer perspective.
The Passport from Foundation is another really nice walet/signer. I haven't used one, so I can only judge based on the specs, reviews, and video walkthroughs I've seen, but the Passport, and soon the Passport Prime, are the Cadillac of hardware wallets. Their design is beautiful, and you can tell they're appealing to the high-value users. But with the Cadillac design comes a Cadillac price. It won't be an issue for people holding dozens of BTC, but for the average bitcoiner, it may seem intimidating.
I really like the design and functionality of the Portal. Using the NFC connection to power the device is ingenious, as it always works, and you never have to be concerned about dead batteries, or being near an outlet to conduct business. It looks like a very sleek, and efficient signer, and at $95 and considering its ease of use, it's accessible to everyone. What I don't like about it is that it's 100% NFC. It doesn't do true air-gapped transfers via QR or transaction files on a MicroSD. It's probably not a dealbreaker, especially if you do all or most of your transactions on your phone, but I like having options as it makes the device more versatile, and more easily used across platforms.
I've also been looking into the SeedSigner. It's a nifty little Raspberry Pi Zero project that you can build yourself, or purchase fully assembled. It has its own OS, and it's purpose-built to conduct true air-gapped transactions using a small screen that displays QR codes, and a small camera on the back that scans QR codes provided by your companion software wallet. It also backs up to MicroSD makings backups easy. The SeedSigner costs about $85 assembled and with an SD card, and the DIY kit ends up costing about $10 less. But there's downsides to every hardware wallet, and with SeedSigner the downside is no secure element chip. Instead, it relies on the software, and embedded microprocessor to protect the seeds. For this reason, I think it's a great choice for people holding less than 1 BTC, but probably not ideal for those holding larger sums. It's a great introductory signer for people new to bitcoin.
Given that SeedSigner's cost is similar to Portal, I think it's a toss-up between Portal and SeedSigner. Is it more important to have a secure element and a professionally manufactured device, or is it more important to have true air-gapped transaction signing? That's what I have to determine for myself.
