Framework has some quality problems, not everyone is a fan of the keyboard, and it’s relatively expensive.
Tuxedo is quite good, but they often use stock Clevo models and customize them, so they might be cheaper and not that well designed than one by a “proper brand”.
Not sure about the rest.
There’s very little alternative if you want a ThinkPad style keyboard and track pad/trackpoint for the price of a used or older ThinkPad.
