Cobi Concorde
I'm surprised nobody has mentioned the Cobi Concorde yet, which has been available for quite some time: https://cobi.eu/product/concorde-g-bbdg,2615
It's not as sturdy and sophisticated as the Lego Concorde, but it does have its merits. The wings have two layers of plate bricks with slanted surfaces, while on the Lego Concorde, they're constructed from a flat wall.
Lego on the other hand gets extra points for the landing gear: On the Cobi, it can be folded, but not tucked away, and the mounting is quite fragile.
