In a swept wing jet aircraft when you are on final approach you are in the 'speed unstable' area at the back of the drag curve - whereby any loss in speed increases your induced drag further. This means that speed can bleed off very quickly if you're not careful...

In the go-around the general rule is that a jet aircraft relies more on the retraction of high-lift devices as a quicker response than the engines spooling up as this can take some time, in comparison to the more or less instantaneous response of a piston engine.

Piston engine aircraft approach apeeds are further along the drag curve and are in the flat speed stable area of the drag curve. Any minor reduction in airspeed shouldn't make a vast difference to handling etc. Thus, it may seem easier to land a piston than a jet.
