Hyper-V converting virtual hard disk type

Hyper-V provided access to three types of disks fixed size, dynamically expanding and passthrough

Caution:
Cannot convert disks with sanpshots attached
This is not a conversion it is a copy therefore ensure you have enough disk space

Question:
I have seen it quoted that with the RC version of Windows 2008/Hyper-V the fixed disk was about 3 times faster than the dynamic. In later releases there was no real performance gap.

Is it worth converting dynamic to fixed if so what are the advantages?
