The old pins weren't ideal (for example the player pin disappearing behind the location pin) but the new ones are clearly worse. Aesthetic aspects apart, you often have to zoom in a lot more to understand who clicked where and if your guess was good (especially with animations off), which also makes it worse content if that's something you value. Some have suggested leaving the option to keep the old pins, which is not bad, but I can imagine that there are other viable options.
