To have complex handling is not the same as to have poor dynamics
The 737 is unbalanced and has poor dynamics while that fighter jet is perfectly balanced and has great dynamics, the complexity in its handling is there to explore to the max its inherent dynamic qualities.
Unfortunate comparison, the 737 is a geriatric machine it's one of a series of modifications on a design that was first used 60 years ago, by comparing it to a well designed modern machine you just made it look even worse.
Besides, where's the point in comparing one to the other, they are totally different things!!!
