It would do a lot to reduce the amount of single use plastic packaging.

It always depends to what scale you chose to measure the harm. Environmental plastic pollution? Sure plastic is way worse. Less broken glass on the sidewalk? Now that plastic is saving your kid and your dog a hospital trip. We are also assuming making the glass bottle is more environmentally friendly than making the plastic one.

Throwing plastic bottles on the sidewalk is plain littering. Throwing glass bottles is not just littering. Someone throwing glass bottles around definitely knows what he's doing and should be dealt with accordingly
