I'm still using the Vizio P-50C1 4K display. I've been keeping an eye out for used Sony X900E units, but haven't come across any locally. That display has an option for perfect 1080p to 4K scaling and otherwise seems to be a solid display.
The Vizio is quite good and for all intents and purposes my "blurry" issue is mostly an artifact of my obsessiveness. In practice, at a normal sitting distance, you can't actually discern the slight "blur" that exists and even then, it's only detectable on certain content. The best way to describe the issue is if you have a 720p display (actually a 768p one marketed as 720p) and switch the content from 720p to 768p, the crispness and precision goes up considerably. The upscaled content on this Vizio has similar characteristics. I noticed it most when displaying the ANSI-based menus of the Raspberry Pi. If a pixel-perfect 720p/1080p to 4K affordable scaler emerges, I may check it out, but I'm otherwise content.
In addition to the XPC-4, I also just received an OSSC. The OSSC is quite compatible with the Vizio and all of the noted 'problematic' scales work great on the display. When contrasting the OSSC with the Framemeister, the OSSC seems superior to the Framemeister - clearer and crisper. I have not yet played around with FBX's FM profiles, so I am wondering whether if I switch to those, the gap between the OSSC and the Framemeister will go away. (That being said, from a usability perspective, if I don't need to switch profiles on the OSSC and 'it just works', I would give the OSSC the edge.)
The Lumagen remains the most versatile device I've tested. It handles everything exceptionally well. Its lack of scanline support is my biggest issue with it, and similar to my comments on the OSSC/FM, I think the OSSC may be better for 240p content. I need to do some actual side-by-side tests so I can feel more comfortable with that assertion. Echoing what Fudoh has documented, I've found the Lumagen is a better option for 480p content.
Given that some of these devices have a slight edge in certain scenarios, I'm working on making them all available to my display. I've got a combination of a 1x8 SCART amplifier and an 8x8 VGA matrix switcher that can route everything to my Vizio and my CRTs.
