Simviation, what bugs you about some addons/What decides if they will stay in your hangar?

I always wondered peoples standards for aircraft they download, whether it be freeware or payware. What decides if it is an aircraft you like? For me its usually the textures, and for that reason, I can't stand PAD's aircraft(no offense to them), they just look so unrealistic. Another thing would be the landing gear animation. I have not found an A330 for fs that accurately simulates the gear animation for it. I really hate when landing gear sinks into the runway. After all, touchdown is the most fun part, and the gear are the star of the show. Anyway, lets hear your thoughts.
