The ThiEYE T5 Edge is very slightly better than the V50 in almost every way (lens, stabilisation, user interface), but it’s not enough to justify the 30% higher price on Amazon. The V50 has a more rounded accessory package too. If you can get a deal from an overseas seller the Edge is a marginally better cam, otherwise stick with whatever is cheaper on Amazon.
The T5 Edge is currently only 10 GBP more on Amazon UK (and that’s worth it imho but 30+ difference isn’t)
Author’s note: I forgot to note when I showed a cropped 4K and 2.7K sample, so if you’re wondering why the quality of those two shots are so poor, now you know. They’re cropped in!
