I have SPD on one side/platform on the other, but only because I don't always love wearing my cycling shoes on rides with my kids which can turn into playground visits/library visits/convenience store runs/hikes, you name it, not because I commute on the platform side.

I always commute with SPD side, never had a problem getting out. If out and need to get back in real quick I just choose not to worry about it until I am through the intersection or whatever. My shoes have thick lugs so they grip either side of the pedal ok until I can get situated.

I ride in the city but it's LONG stretches on MUP/dedicated bike lane with only 1 serious intersection. I may have different points of view if I was going through more stoplights.

THAT SAID - I just ordered a new bike and, with it, hot pink platform pedals (my daughter talked me in to it) SO we'll see how I like riding those for a while. If I hate it, I'll just throw my SPD pedals back on and call it good.
