For me it all depends on what you want to use.
If you take the time to learn the harder combos, then more power to you. Even if these combos don't end being used much (like Mu's harder but cooler looking combo with multiple charged lasers), it's probably more satisfying for pulling those off and the reward might be slightly higher damage and heatgain
But some people rather use easier combos for being more practical, because under pressure you can make mistakes more easily and they don't want to risk dropping combos
Either way, nobody is wrong for doing whatever they want
