Metabones speedbooster vs viltrox ef-m2 in the GH5

I've had the Viltrox EF-M2 for about 6 months and never really tried it out until recently. I did some testing to see how it compares to the Metabones Speedbooster.
Do you have either adapter? Do you think there is a reason to purchase one over the other?
