It all depends on your style and preference.
I've used clipless for years. Most of my riding was XC trails with the occasional jump or drop. Clipless pedals are much better suited for XC type riding where speed and efficiency are critical. Also, having clipless provided me with more confidence on steep climbs. For racing, they are almost a necessity!
In the last 2-3 years my riding has become more aggressive with bigger drops and some stunts. So, I switched back to platforms in order to be able to get off the bike quicker.
So, it all depends.
