Which traffic program?

Ok, I've been looking at the big three payware traffic programs. I'm curious which offers the best ballance of:1. Models easy on the framerates that also look ok2. Parking updates so that parking is realistic (i.e. airlines at their own terminals etc) so I don't have to spend a day downloading afcads and installing them.Also, Just Flight's Traffic 2005 contains code to help manage the flow of AI into busy aifields. Does this work? Is it worth considering on this facet alone? And, are there freeware programs that can get the planes off the runways faster so you might not need it?Thanks all for your help.
