Not trying to flame anybody, your experience is your experience. But the whole clipless/platform argument is a waste.

If you want to try them, try them (clipless); if not, don't. The biggest, and only true, advantage of one over the other is making your ride experience a better one in your own opinion. One of my buds rode clipless, and swore by them. Another swore AT them.

I ride clipless because I ride better with them. I like the 'connected' feeling to the bike, it's like it talks to me during the ride. I'm not just clicked in, I'm plugged in. I've since tried platforms, and the week I rode them was the most painful in recent memory, worse even than the collarbone that shattered. Leg cramps and shooting calf pains that would not quit until the 2nd day back on clipless.

Am I faster? Likely so, since I'm faster across town now than when I was 16, by the clock. Lower top speed, better cruising speed, I guess. Does it matter? No. As long as the ride is enjoyable, I get my business done, and I don't get hurt, each ride is a success.
