I haven’t tried tanstack-start, but I wouldn’t be surprised it becomes the defacto react framework instead of next. Everything by Tanner Linsley is just so well thought out and the DX is amazing. If his framework is the same level of quality, without any major gaps compared to next, it will probably blow next out of the water.

And Tanner is already a huge name in the typescript/react world, so I think there is actually a chance.
