It depends on what you are planning to use the extra channel for.
6 GHz has higher theoretical bandwidth, but lower range. Depending on how far you are from the router, you might get better real bandwidth from 5 GHz. If you live in an area with high population density, 6 GHz is less crowded than 5 GHz - both due to the lower range and fewer people owning 6 GHz-capable routers. In that case you might get more consistent latency from 6 GHz since there is less channel contention.
I want to give the extra channel to a VR headset, which I always use near the router and only care about the latency aspect, so I'd prefer 6 GHz. However, I imagine that a lot of people want the extra channel as backhaul for a mesh network in a large house, and in that case the increased range of 5 GHz might be preferable. So it's kind of a weird situation where the non-Pro may be better than the Pro for the majority of users.
If you don't have a specific use case for the extra channel in mind already, then it very likely doesn't matter, and you might be better off with a tri-band router.
