Casual observation. 類友 is a colloquial contraction of the proverb 類は友を呼ぶ ('like attracts like,' literally 'the kind calls its friends') — the equivalent of English 'birds of a feather flock together.' ~と言うよりは 'rather than saying X' is a common contrastive construction for choosing between two characterizations. 似てくる uses ~てくる for a gradual coming-into-resemblance over time.
