There's a few reasons to say they're junk:
1. Stacking - ever go quickly over sequential bumps and notice how they progressively get harsher?
2. Inconsistency - the same two shocks won't perform the same
3. The paint
4. Lacking Consistent performance over obstacles taking away stability.
It's not all relative. You can prefer that ride all you want, but the reality is what it is - it may just not matter for what people that like ranchos do.
what bolt-on shocks are better?
