difenately if you can afford rodi go with it, as using tap water is imo more for someone that can identify problems and solve them fast. There is no room for error using tap water and 1 extra fish or coral that requires feeding/poo's can throw things out of whack in a hurry. Not to mention the fish's growth etc

Wouldn't even consider it in a reef tank, trace elements like copper from your house pipes will slowly build up in the tank and eventually absorbed in the live rock poisoning your invertebrates etc..
My local water (GVRD) is around 12-15 ppm and I use strictly DI
