As Yep said, it really depends on whose zones you're comparing.
If I ride Coggan L2 (Endurance) - since his L1 is active recovery - my heart rate will always be in Friel's HR zone 1. If I ride Coggan L3, then my heart rate is Friel zone 2-3, etc...
Another reason why I like Stern's zones, because active recovery is active recovery - in both worlds. Here's my ride from Friday - nice and steady rhythm, not a lot of stopping or moving around, just steady pedaling. The yellow dash lines would represent the lines at the top of Coggan L1, L2, and L3. The red lines are the tops of Friel HR Zone 1 and Zone 2. This was the first time in two weeks I'd even ridden with the HR strap on.
Edited to add: To further be a shill for the Stern zones, here's the distribution charts for the two (power/HR). I don't normally pay these much mind because they can be very deceiving (not accounting or steady time in zone), but when comparing over a whole ride they can have their use.
(should also add that the zones for Stern in Cyclingpeaks don't account for the Zone overlap as he defines them, but .. well. like I said, I don't really pay much attention to the distribution charts.)
