Hose Free Eco Wash is more concentrated and feels more like a soap than ONR. I haven't used v3 of ONR but compared to v2, the chemical guys wash is much thicker feeling.
Both are slick though. ONR seems to wipe off a bit easier though.
They both work about the same. the cg has suds when you wash, and your wash media doesn't stain as bad. other than that I haven't noticed much difference.
