It’s a ‘horses for courses’ situation. If you believe a pivoting head solves your problem, it probably will. I’ve been using sliding headstock machines for a couple of decades now - the setup is quick and simple and allows full access for what I need to do. The clamping mechanism on my lathe is truly robust with a clamp that’s basically the size of the headstock footprint. Adding a pivot necessitates finding a good secure way to support the toolrest in addition to machining a well designed pivot and locking system. As with anything that involves engineering to achieve, the cheapest solutions are often the most problematic and should be avoided.
In the long run, get what solves your problems and allows you to do the work you wish to do at the best level of comfort and security.
By the way, an acquaintance several years ago bought a Titan Magma lathe - what a beautiful, well-designed piece of equipment. He passed a while back and his club in Olympia was tasked with helping his widow liquidate his shop. I didn’t hear what it sold for, or even how he managed to import it…but it was a nice lathe with all the bells and whistles.
