No, you want the next generation, for the same reason: Thunderbolt is now officially dead, it has been absorbed into the official USB4 standard.

There is very unclear support for existing Thunderbolt-over-Type-C devices under USB4, and it is likely your devices will stop working.

Please wait until USB4 and USB4-based solutions start shipping before you start adopting it, else you're going to be stuck with a bunch of devices that are no longer being supported, or cannot be cross-supported across Thunderbolt 3 and USB4 variants.

>Thunderbolt is now officially dead

There is, actually Thunderbolt 4. It is in no way dead. To what extend this is different to TB3 is unclear yet.

>it has been absorbed into the official USB4 standard.

Not Strictly true. TB is not a mandatory part of USB 4 standard. Which means you will likely have lots of USB 4 controller without TB support. ( Cause It will be cheaper )

>There is very unclear support for existing Thunderbolt-over-Type-C devices under USB4

It will work as long as your USB4 has support and certified with TB. You will have to use a TB cable ( which you should have if you are already using it ) instead of any USB-C cable.

How exactly will TB certification works without involving Intel is still unclear.

I already have a bunch of TB3 Docks in our company, so ditching them would really be painful and a reason to stick to Intel.

Intel's own version of their USB4 controller might not support it either.

Absolutely nobody I know has been able to get a straight answer out of anyone; not Intel, not the USB IF, not other members of the USB IF, on if existing Thunderbolt 3 devices will work on USB4 hosts.

And it will be a complete and absolute shitshow if it doesn't, because Type-C has swindled us into thinking Type-C is just Type-C.
