Never used an FPGA console before...my take
I got my superstation one two days ago. I've been emulating since nesticle in the 90s in one way or another so I've experienced the good and bad. Always wanted to get a mister but could never justify the cost so when this was pitched to me as a nice complete system at half the cost I made my first preorder since the original xbox.
I love it, I got the dock but cd's were an afterthought for me, I'll try to add an nvme drive and maybe get a snac adapter or 2. Setting it up was pretty easy, if there was confusion about bios I just ran it by chatgpt and it would even verify the hashes for me, what a time to be alive.
The emulation just "feels" right. I've been playing rayman on ps1, Rondo of blood, In the hunt, Mark of the wolves, and exploring old cdi "games". It's such a nice little package, I actually enjoy the bare metal interface, and the mame setup is actually making me slow down and only add the games I want. I could see a world where I just get a spare superstation and sell off my retro consoles.
If your pretty casual with gaming like me and reasonably good at following instructions, I highly recommend it. There are definitely areas that were rushed to get it out, but I would still get it again in it's current state in a heartbeat.
