Having the same issue and due to the tightness of all the linkages, yeah, it's not fun. I'm also not a fan of the sway chains either, always having to adjust them for each implement. Definitely having to make some kind of spreader bar or mechanism there.
I like the look of the Pat's but it doesn't seem to help the top link connection at all so it cuts the work down by 2/3.
The LandPride/Speedco/HF/NT units deal with all 3 but then have fixed width issues so the implements need to be modded, and if you have a swiveling toplink (like is on most rotary mowers) you need to treat the connection a bit different. So these aren't a silver bullet either.
Short of a 'smart' 3 point hitch, we're essentially patching 1950's tech with some modern conveniences.
To be honest, the industry really should adopt a set of standards so that the connection points, the PTO location, etc. is always in the same spot. Then you could design a true passive 3 point quick hitch. Without that though, we need to find a way to make the hitch smarter or our backs tougher... HAHA!
