Hi,
AK Models is here; I personally have flown all three Direct connections F-20 and F-18 as well as my MIG-29.
Not to make a commercial out of this but here is what I have to say.
Both planes from DC are very good flying planes. F-20 seems to be little lighter on the stick. It is fast and fun to fly, lands very nice too.
F-18 is a show stopper with a hot engine (ENYA 80XF was used on mine), I fount it to be little heavy (in stock configuration) so I have added many lightning hole to all formers and ribs and moved all servos back for easy balancing. So it came out to be at least 1 lb lighter than other F-18 out there. After all this you would still have to be very careful on the take-offs and landings (not to pull-up too fast and not to slow down too much). MIG-29 was created using best sides of both airplanes (F-20 and F-18).
It is very responsive to the sticks, very stable. Depending on the engine it would go very fast as well. For more info please see: http://ak-models.com/planes.htm and/or current owner’s website with videos of them fly at: http://home.swbell.net/swmeier/

It did sound like a commercial, didn’t it?

Good luck with your decision.
