I like them when they add up perfectly and we don’t have to make up an excuse for the excess (like when “Torah” adds up to 611 and we have to explain why it’s just so darn close to 613, but not quite).
One of my favorites: Eim (mother) = 41. Av (father) = 3. Thus, eim plus av is 44, which is exactly the numerical value of yeled (child). 44 Is also the number of autosomes (non-gender chromosomes) in the human body. Imma and abba (with their irregular spelling) would add up to 46: the total number of chromosomes in humans.
