The battery does nice up to 20A with acceptable tracking between the cells and nearly constant capacity, but it cannot do 30A.

The button top version has slightly higher resistance due to the button top. This is only significant well above 10A.

These two cells do also track very nicely.

Conclusion

The battery is a acceptable high current cell, at least up to 20A, but the capacity cannot match the newer high current cells.
