I have Korbel (Japan), Innerforce Layer ALC (let's just say IL ALC) and Apolonia ZLC (basically a Franziska ZLC).
The above observations are correct: IL ALC and Apolonia ZLC are controllable in short game, service and service receive, just like all wood. The difference is only when you hit harder, that's when the composite kick in. So basically a Korbel on steroid.
Now, Korbel head size is 158 x 152 mm. IL ALC is more standard, only 157 x 150 mm. Therefore initially you will feel that IL ALC is a bit stiffer. On the other hand, Harimoto ALC head size is ~158 x 152 mm, similar to Korbel. So you might feel more familiar with Harimoto ALC in the beginning (coming from Korbel).
Apolonia ZLC head size is also 157 x 150 mm, but instead of 5.9 - 6.0 mm in thickness (like Korbel and IL ALC), its thickness is only 5.6-5.7 mm. So, even though it has Zylon Carbon, but it is not far different from a Korbel. I even feel that Apolonia ZLC is more similar to Korbel (but with "steroid" factor) compared to IL ALC in the beginning. The reason is that the arylate has this dampening feel.
I do not try to confuse you if you have decided to get IL ALC. IL ALC, Harimoto ALC and Apolonia ZLC are good blades. You will be fine with any of them.
