Boyfriend constantly comparing his son's to mine

I have a 14 year old from a previous marriage. My boy has a 14 and 16 year old. My son doesn't have many friends. He has maybe 2 but he doesn't really hang out with people that much. He enjoys arts mangas, and trees. We live near woods and he's always in the wood climbing tree. He likes nature and stays in trees to draw and read. I honestly think he may also be a little autistic. My boyfriend's son's are both very popular and well liked. They always have people over but honestly when their friends are over they're all just around each other on their phones. Sometimes they get off the phone to play video games together but they're mainly on their phones. My boyfriend is always saying how his son's have more friends than mine and saying my son should be more his. He compares them and says his son's are more well liked, his son's are popular. They have many friends. He's constantly comparing them and also saying how my son is weird. He thinks my son should be more like his and it annoys me.
