The Yuht aren't really all that much to write home about in my book.
But I just don't understand why people dislike the Zroni. It's just pretty much universally extremely good for any empire with the economic boost. Need an extra 50000 alloys on no notice to support an emergency fleet build up for an unexpected war on an ally? No problem if you have that giant Zro stockpile... even the Cybrex War-Forge, which I agree is pretty good & especially so with the recent rework of it, takes a lot longer to produce zounds of alloys than just having a huge stockpile of a resource to trade (with virtually no downside to you!) to practically every other AI empire for anything you need.
