I have owned and used the Technikardan 45 pre-S (exact same camera as the S but without the zero detents), Technica 4, Sinar P and P2, Horseman, Toyo CF, VX125 and GX, Arca F Metric and Monolith, Ebony 45 SU (non-folder), Shen Hao 45, Phillips 45 and the Chamonix 45.
With 4x5 film, I would not hesitate to repurchase again for field use the Tecnikardan, Toyo VX125, Arca F Metric, Ebony 45 SU or Chamonix, but would lean to the Ebony or Chamonix due to total weight, compactness and ease of use. The downside to the Ebony is it has asymmetrical rear tilt and swing and the axis is off most MF film -- and if I got back into using a camera with movements, I'd probably want to use MF film with it since I already own an excellent MF scanner.
However with digital, the list narrows quickly. Here none of them really have precise enough locks and movements for MF digital IMO, though if I were pressed the Arca F-Metric would probably get the nod for its combination of precision and rigidity. It is more rigid than either the TK or Toyo VX, as fast as the Toyo and faster than the TK to set up. The TK is least rigid when extended but the most compact of the three when folded. I don't like the fact you have only base tilts with the Toyo VX, and much prefer the axis tilts on the TK, and with the Arca FM with Orbix, you get both base and axial tilts. All are excellent build quality and run about the same weight, all have graflok compatible backs.
The Tech IV/V/Master are great, rigid cameras, but not as flexible to adjust and more fussy when using lenses shorter than 90mm (you have to drop the bed which takes some time and you then lose rise)...
All said and done, if I were going back to a camera with full movements, I would shoot mostly MF film and so probably get another Chamonix...
Sidebar note on the TK -- if you get one, practice folding it several times first with the bellows REMOVED! I can almost guarantee you will wrinkle the bellows of the TK the first few times you try to fold it with the bellows on...
