Assuming cost has to be considered the 3racing F1-09 is the easy winner. You need the alloy front castor adjuster; without it the front end has so much slop and tweak its useless. And adding the F104 diff and axle so that you can remove the wheels without losing the diff setting is also an essential upgrade in my opinion. But the kit and those upgrades will only cost you about £130, which beats the other cars hands down.
