None of these bikes are typically equipped with lockout so I don't get your point?
If you are talking about Propedal, its not a lockout its compression damping and almost all shocks have some form, adjustable or not. Fox sells different tunes and typically DW and VPP bikes need minimal compression damping as its built in to their design. Most mid to high-end builders like SC, Turner, etc offer a choice of shocks which changes over the years for a variety of reasons.
Motorcycles are primarily single pivot linkage designs with the rear shock doing most of the work rather than focusing on suspension design. There are many ways to get a good design.
Today its not as distinct as the early days of FS when there were some clearly faulty designs.
Best to focus on fit and geometry. Also customer service is important and Turner has some of the best. I know from personal experience SC has always been very very slow to fill orders and customer service isn't much quicker.
Note, the last bike bike I bought was a SC (my second SC in fact). I also still own a Turner (my first) and Specialized (my forth). I also have a Gary Fisher (my second Trek product) as a commuter.
