I've tried a number of platform pedals over the years. Cheap bearings and/or bearing seals have been the biggest annoyance. I ride a lot of dirt roads and trails and when fine dust gets into the bearings, that's when you get that tick/click with every rotation of the cranks. The only way to clear that up is to take the pedal apart to clean and lube the bearings and races or replace the bearings altogether. It's happened on road riding bikes I've owned too. Here in the Northeast, at this time of year there's a lot of fine debris on the road.
I've been riding
Xpedo Spry, all mountain/downhill platform pedal since the middle of last summer. Magnesium, large platform, low profile with more grip. I really like them. Double sealed bearings and good protection from the ultra fine limestone dust on the local trails.

There are a lot of other reviews, some by road and hybrid bike users. The Spry made a big splash when they hit the market, offering a pedal that compared well to others costing 3 times as much. Xpedo only makes pedals and has been doing so for more than 30 years.
Another good choice for platforms are
Crank Brothers Large Stamp. There's the huge Large Stamp for big feet, CB also offers the Small Stamp. The large was my runner-up to the Spry, as I wear 11 to 11-1/2 shoes. People seem to like the offerings by Crank Brothers.
For the budget conscience the
Wellgo MG-1 are good for the money. Magnesium, sealed bearing platform pedals with reflectors. I've had them on another bike for a couple years and they've performed good.
One thing that gets hidden within the specs of some pedals is the use of bushings instead of bearings. Some have two bushings and no bearings, some one and one. I'm not a huge fan of pedals using bushings over bearings. It's a cost saving measure, but they don't perform as good as bearings and tend to wear out quicker.
