There are surely some.
But I would expect most people that like her simply because of screen time would go Nami's direction more than Bella.
Bella's personality is quite strong. She is way more to generate extreme like (love in those of us touched by the force) or extreme dislike.
Nami, on the other hand, is more an universally likeable character. You can find people disliking Bella (heretics whose dayd are counted), but pretty much everyone likes Nami.
So, if it is just because of screen time, my guess is they would prefer Nami. Hey, even in Bella's path Nami crying out of painful jealousy is quite a powerful scene for her. I pity her, but changes nothing to me. Bella is the only one, "even if this world has to end" (Quoting Solas)
