1972 DODGE DART Wiring Kits

So I have a 72 Dart with a Slant-6 225CID. Its a 4 door sedan(I'll try to post pictures later). This is my first MOPAR and I have plans to put a 340 in it but that's a little ways off for now. I was wondering what the best kind of re-wiring kit/system was, that's also cost effective? I've heard of YearOne and PAINLESS, but don't know too much about them. Any opinions on those as well?
