FPGAs have their use.
They are more compact than any PC powerful enough to do as accurate emulation.
They are more efficient, power wise. A regular CPU needs to draw more power to deliver the same amount of emulation accuracy.
They don't have an OS, so they don't have the additional input lag one can cause.
It's easier to use an old CRT TV with them.
Other than that, yeah, i agree with you.
And it's a problem with youtube retro collectors specifically. They know nothing about emulation because they tend to only use things they can have in physical form. So if someone tells them emulators suck and FPGAs can cure cancer, they will believe it. Which is how this "FPGAs are more accurate"myth actually came to be. It was the Analogue marketing that started it.
It's even worse when you see youtubers trying to do FPGA vs Emulation comparisons themselves (because content) and you instantly notice they don't know any better because they rarely even use accurate emulators (or at least accurate settings) in such comparisons. 99% of the time they use the first emulator that comes after a google search or they just compare them with whatever emulators the Raspberry Pi uses (which is the weakest device one can use, so the emulators are always performance based) and maybe some equally crappy android or Chinese cheap devices.
