Turkey bacon is a bit more healthier than pork bacon because turkey bacon contains less fat than pork bacon and is also lower in calories than pork bacon is.
However Turkey bacon has less protein in it than pork bacon does so it could be healthier to eat pork bacon in moderation than it is to eat Turkey bacon.
But overall the Turkey Bacon would win as the healthier of the two bacon kinds but I hate Turkey bacon so I will stick with my beloved pork bacon even though it's less healthy.
