Verdict

A generation apart: Klipsch Reference R 605FA is the newer design, against a 2018 model. Newer is not automatically better, but the older one is more likely to be discounted or near run-out.

Area	Better	Why
Bass	evenly matched	Much the same reach (38Hz vs 38Hz).
Amplifier needs	evenly matched	Similar sensitivity (96dB vs 96dB) - both want much the same power.
Size	depends	Similar cabinet size - neither is easier to fit.
Expandability	B	Klipsch R-625FA: Atmos drivers.

A Klipsch Reference R 605FA B Klipsch R-625FA
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.

Which should you choose?

Klipsch R-625FA has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does.

And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
