Topeak MTX vs Ibera PakRak bike bag - Grocery loading challenge - Review

I try stuffing as many grocery items as possible into two different bike bags to see how they compare.

I have the larger ibera panniers, absolutely love them.

Iwent from bontrager bags to ibera and absolutely love the ibera. Dont get me wrong, the rear bontrager was 8 years old, still usable but pretty beat up as for uv rotted. Im hoping the ibera plastic snaps hold up at least 5+ years .

Which one would you recommend?

[@spinundated]

I prefer the Topeak because it holds more overall.

Can the Topeak and Ibera both use the same rack?
