Which generally overlooked townie makes pretty children?

I love Diego Lobo and used him as partner for my first drifter house. They had 5 or 6 children and none of them were really.... attractive.
One overlooked townie imo is Liberty Lee. I absolutely hated her for her stupid hair but after putting up a bit of makeup and different hair she was stunning. Combined with Akira Kibo genes they had beautiful children

When I start a game I go straight to manage households right after I have my sim established. There I age up baby girl with the Delgato Household. Sorry I can never remember her name. I start pairing couples up. Akira and Diego are a few of the ones I hook up with other Sims. I don't want the Dennis Kim effect to happen so the only thing I can think of to eliminate that is by pairing off many sims in the beginning and create townies to avoid them from spawning. Usually, I pair Ms Faust and Diego up and use genetics to give them at least one kid. I randomly hook Akira up with someone and give them a few kids.

Not directly townies, but the couple from the Vintage Glamour trailer creates wonderful children. You can download them from Maxis Creator.

I’ve used J Huntington and he makes decent looking kids...I’m in the midst of one of my sims starting a relationship with Sergio from bro house in Windenburg to see what comes out of that.

I second JC on J Huntington. I had my female sim (who is now happily married to another townie) start out being a little, well, free and easy with the woohoo, and she had several townie babies with different guys, including four with J, aside from that J also is now married to my sim's daughter (not by him obviously, by Johnny Zest), and J has a couple of kids by her now too. (Yes, I made this family a bit scandalous lol). Anyway all of the kids are attractive. She actually had pretty good looking kids with Don and Mortimer too, but I think the kids with J turned out the most consistently attractive. It probably helps that she's really pretty too, but I think J has good genetics also.

I've used a few that have had some cute kids. I pair them off with my own sims. Don, J and Johnny Zest make cute kids. Paolo can too if you shave off a fair bit of his chin first. Salim Benali, Sergio Romero and Travis Scott also make cute kids.

Liberty Lee has had some ridiculously cute kids in my game. Her and Travis Scott make some of the best little simmies together.

Diego does make some cute kids but only if they don't inherit his mouth.
Some other potentials are: Luna Villarreal, Morgan Fyres and surprisingly enough, Malcolm Landgraab, though I change his hair colour from that cheesey yellow to match his dad. Johnny Landgraab also makes decent kids. Cassandra Goth, with a little makeup and different hair is quite the looker and in my game, she married one of my main sims and they had good looking kids.

I think Johnny Zest makes pretty cute kids ☺

I really like Liberty Lee and Ulrike Faust. I have had a few sims marry them and have kids. All of them came out rather nice.
