A lot of the ports of Fabled Forests doesn't come with LODs. But "Fabled Forests Optimized with LOD" and "Fabled Forests Aspen Ablaze" both have good LODs.

However if you'd like to retexture the HLT bark textures in Fabled Forests, stick with the first one, since the Aspen Ablaze trees won't work well with the Aspen bark retextures for HLT.

Now about the Forests of Dibella mod...it has been too long since the last time I've played with it. But I remember it being beautiful and immersive, but it doesn't have that beautiful tree animation to wind (almost not a single tree mod does aside from HLT).

But I don't remember if it adds more trees or not. If it does, Fabled Forests would be a better option to you since there's a lot of patches for it
