No mincing of words, the Victory Class is an absolute dog at sea. Friend of mine was a CO of one. It has competent systems but basically suffered from trying to do too much with too little. As mentioned by @Tam , crew fatigue was a real issue in anything other than calm seas.
Also as mentioned, there is really no need to shoehorn a DDG into a Corvette unless constrains dictate you do so. As alluded by @MarKoz81 , one possible reason for the tight packaging of the Sa'ar 6 could be pier constraints as well a mission set that doesn't require blue water persistence. It has been publicly stated that the Sa'ar 6 and the C-Dome on it is primarily for maritime infrastructure defence.
Since the Singapore Navy Victory Class has been brought up, I'll point out the parallels ...
The Victory Class was planned and delivered when the sole Naval Base was the Brani Naval Base. I frequently caught a view of this facility when visiting Sentosa and believe me it was one super cramped naval base. Since then, the RSN has expanded their facilities, moving out of Brani and into 2 new bases including Changi Naval base which has berthing capability for even a CV.
The idea of "not enough space" for infrastructure expansion may seem ludricous if you come from a big country (like China) but it is a problem that small countries face. Give you an example ... to a Singaporean, a 30 minutes drive is really a long drive. You could drive from one end of Singapore to the other end in 30mins. Needless to say, we get laughed at when we say that overseas. To some, like in the Aussie outbacks, it's literally just around the corner.
Luckily, for Singapore, "not enough money" is not one of the problems it faces, so it built new bases. 2 of them.
The RSN has also evolved it's mission of sovereign maritime security from simple coastal security to a much more ambitious one of SLOC security. The Victory was fit for purpose for the former but shows it's limitations when tasked with the later.
Just look at the size of the "replacement" class for the Victory - the MRCV is literally an order of magnitude bigger. You can trace the hand-in-hand growth of the platforms in the RSN, from "armed to the ills compact" designs to a more "spacious" blue water capable ships, with the parallel growth in infrastructure and mission set. None came before the other, they are all intertwined.
Will China ever need to design something so densely packed? Probably only for littoral comabatants?
