A craftsmen is never disserviced from having multiple tools in their toolbox and mastery of them all. With experience comes the wisdom and intuition of knowing which tool is appropriate for the problem at hand. Whether it matters how quickly you need to deliver or what level of performance is needed. Inevitably in any engineering problem, there are always multiple solutions, but having appropriate information to make a qualified judgement to provide a sufficient solution as cheaply as possible (often, in software, this may be qualified in terms of time to market) that meets stated requirements (functional requirements, performance - i.e. load, latency & minimal hardware requirements).
