The low travel on the keys is probably the issue. The machine gun sound of your typing is probably because of long travel with speed making a lot of force hitting the key bed, so having a longer travel will probably help there. Also, chiclet keys are really different to standard keys, they are super flat and have no centering dip so you tend to slide to the edges and have reduced accuracy. Add that to the dense layout and you have a recipe for disastrous typing.
