I did look into the over-rail and under-rail monorail systems quite a bit including the non-Plarail sets you pictured. All the over-rail Plarail Monorails have a very noticeable 'wobble' as they travel along and is the reason I have not purchased any except...for the Disney 25th Anniversary release well...because its Disney and...its the Rare one 
. Plarail did final release an updated over-rail Monorail and corrected the 'wobble' in its last release, the 2015 Plarail Expo Exclusive Tokyo Monorail 10000 Series. But this corrected release, which runs the best IMO, come with one drawback from the wobbly ones...the new one can not navigated the special 'sloped' rails and this is probably due to their beefier couplers or just something Plarail didn't think of when designing it. All the other over-railers work fine on the slopes. You may find some info that will help you in this Thread https://www.blueplastictracks.com/showth...t=Monorail Suzukawas video below shows very well the difference between the new Expo Exclusive and a wobbler.
As far as the non-Plarail version you mention and pictured, they are the best and most realistic of any Disney Monorail and they also make some Disney attractions to go along with it. The best being the Contemporary Hotel where the Monorail runs through it. I was all set to purchase one of those until I found the only complaint about them......the set takes up a lot of space probably due to the long radius curves with no options to reduce the footprint and not much options other than a circle or oval Layout. The Plarail Monorails can be set up in a smaller footprint plus has the option to have the rail go in all types of direction up, down, right, left. The under-rail (hanging) Plarail Monorails have no problems at least with the ones I have (blue, red and yellow).
