I don't think it's even cool trying to compare both, the have there strength and weaknesses even there is still a work around in there weakness. So for me I think you should work with what's more comfortable for you, I have tried both and I will tell you that the are both OK but I will prefer node because it has a brighter future PHP is wearing off doesn't mean people are not still using it, Facebook still run on PHP. So my opinion is go with what you are comfortable with
