Klipsch KG4 or RF3?

Hi All, I am looking to start cobbling together a few decent budget vintage items as I having music withdrawals. I have committed to a NAD 7100 and am looking for some Klipsch speakers.

There are KG4's available locally from a couple sellers asking $200/pair.

Now some RF3's have caught my eye. It is so hard to tell the difference from pictures, stats, etc.

I really lean to the warmer and natural tones. Any insights to be shared will be very appreciated.
