The same pedals do not work for everyone. I started with clipless pedals and the original Looks in 1984 and used everything since then. Only recently went to Speedplays.
Shimano are built like a tank. Look, not so much plus their cleats wear quickly. But at least they are cheap. Neither has very good float. They basically twist on their axis and nothing laterally.
I was a longtime Time user but the self recentering bothers me and I think is bad for my knee. Also not nearly as much float as Speedplays. Plus if you twist on the axis then you get even less lateral float.
Speedplay's eliminated my knee pain especially with my trashed knee. I'm still amazed by that. No more icing my knee after a ride and no more ibuprofen. That's worth the fussy cleat setup and regreasing and lubing and cleat covers. Easily worth it.
I use the Keep on Covers so I never have to take them on and off and it funnels the pedal right into the cleat.
I had multiple professional fits on Shimano's, Looks, and Times over the years btw. In the last few years I've used Shimano Dura-Ace, Look Blades, and Time iClic 1 and 2's.
I don't care about weight within reason and most people who do probably shouldn't. Durability is far more important to me.
