For bottle feed baby, what type of bottle do you prefer to use and why? (Glass or BPA plastic bottle)

I am using hegen bottles. It is neither glass nor BPA free plastic bottle. They are made of a material called tritan. My baby is breastfed baby but he accepts this bottle as the teat are shaped like a breast. For glass bottles, I find that it is too heavy and if baby drops, it might break. For BPA free plastic bottles, I am afraid that if the bottle warmer is too hot, it will melt the bottle and chemicals can enter baby's milk.
