I'd say just go for KYB OEM if it's the standard experience you want. But do make note that a lot of workshops and sparepart shops equate persona absorber to gen2 absorber to waja absorber. So make sure you go to KYB website and download their parts number for persona OEM absorber. Gen2 and waja rear absorbers are somewhat shorter and causes the link bush to crack.

I usually change absorber mountings and absorber covers and whatnot all together but people usually don't bother with them.

One thing to note is on the rear sway bar link bush make sure your foreman don't bolt the nut all the way until the end, the bush will just crack. Ini proton technician teach one.

U change to monroe ? Which one expensive, kyb or monroe ?
