mostly maxis match and clay hairs. I don't mind getting my clothing non maxis match and just going to simsresource for it because the links are relatively clean and don't take a decade and a half to get to the download but the alpha hairs, while beautiful, are frustrating in how they break certain careers (try finding a blond suspect as a detective with alpha hairs...nightmare)
Also, I like to have my genetics pass on to my child sims and its hard to know if they are correctly passing with alpha hairs because they are rarely binned with ea colors and will default to some other random color.
