Decorating and Design - Interior Trim Paint

I need help choosing interior trim paint. I want an alkyd paint in a warm white color. A decorator suggested Benjamin Moore's Linen White. Paint contractors and users say this paint yellows excessively and suggested Glidden's Ultra Traditional. But I prefer the gloss level of Satin Impervo over that of Ultra Traditional. I know that these preferences are subjective but there must be more favorites than pure white, Dove White or Linen White. Pleases tell me your favorites.

I answer a lot of painting questions when it comes to technique but as far as brand names is concerned your best bet is to place this question under painting. They have a lot of professionals there to answer just such a question. I do know that they are not big fans of Benjamin Moore's.
Good Luck!
