This version also has good tracking between the cells and also constant capacity at any load, this looks good.
I expect they are using the same cell, i.e. they must have the same performance.

Conclusion

The batteries has a good capacity for IMR batteries, even though it is lower than rated. The performance is also good, even at much higher current than they are rated for.
There is a very small difference between flat top and button top, the button top increases the resistance slightly.
I will rate this battery acceptable.
