Help me choose the first sim rig

I currently using moza r3 on my desk. The first upgrade i want to make is buying a solid platform. The main rig's i was considering were:

- Trak Racer TR40S 300 euro + 40 euro shipping

- SimXPro X80 around 380 euro shipping free

- next level racing GTRacer 2.0 (since seat is included) 380 euro

- https://simline.eu/pl/stelaze-simracingowe/bs-rig-dynamic-frame

Main question is what option out of this 4 is best, if you have better propositions for slightly more price i would certainly think it over, just keep in mind that it must be available in EU.
