I recommend either if them. Arguably the Honda is better built, but the HuaSheng is no slouch either and costs alot less.
From what I have read the Harbor Freight engines are very good quality, and I would recommend them as well based on all of the positive feedback from the many owners of them on this site. I have no experience with them though.
To cut my rambling short:
If you are going for a complete kit, I recommend an EZM kit first followed closely by the stage III 4GT kit with the 100 tooth solid flywheel and 12 tooth freewheeling output sprocket.
HuaSheng engine for both.
Neither are speed demons, 35 to 38 MPH top speed, But I personally don't want to go that fast on a bicycle anyways.
That's what motorcycles are for.
