Yes, if money was no object I'd go hardwired too. I opted for that with our security system - all hidden sensors and wiring.
One thing to consider with a hardwired system is its longevity. Years ago GE offered a hardwired system. It was eventually discontinued, and I understand difficult to find replacement components today.
So if you choose a hardwired system, look for one that is manufactured by more than one company. X10 was like that years ago, but several of the manufactures have jumped ship, and some of the devices have become difficult to find.
