Horses for courses. If you had speed below S then don't have to retract. Below is from Airbus:
When landing configurationis not established (CONF1 or CONF2) there is no particular need to retract theflaps one step as there is no drag issue, and therefore, no performance impact.However, standard go around procedure (GO AROUND – FLAPS) could be applied,even when in CONF1, provided TOGA detent is reached prior flaps retraction (toensure GO AROUND phase engagement). A/THR and FD’s will maintain VLS, and SlatsAlpha / Speed lock function will inhibit slats retraction if necessary
