which plane is better ,the extra sd models 100cc or the yak qq 100cc?

I love QQ planes and SD models planes I have the SD 33% yak and it is oh so nice. 3d's really well like a foamie. knife edge is strtaight with no coupling, harriers are great too.

I have had the QQ 73" yak and the 100cc Python in the QQ planes. they are extremely nice also. the python is dreamy , one of my all time favorites. If I had to choose, I'd say the SD models since the schemes are nicer and they are still in production.( under the TT toc name) and quique may no longer be making planes.
