I think House has him on overall size, especially in the Soleus muscle. But on detail I think Ben's got him. When it comes to detail, The Houses calves look like huge blobs (not synthol blobs for the record, real muscle and frickin' HUGE), but I think Ben's have a look that is more crisp and detailed and looks like he went through a cheese grater with those things.
Possibly because House hasn't nail conditioning, and he is also smaller than Ben I believe...I'm still pulling for House to be a break out bber in the future...he needs to get his teeth fixed and his upper body to match his wheelers, he'd be straight...Hie has great back detail, and great arms.
