It has been worked on longer and has more extra campaigns and of higher quality. Oblivion has some coding quirks that even now cannot be dealt with, while Morrowind has been completely overhauled, several times. There are mods that can make Morrowind as pretty as Oblivion or better, and it has superior gameplay. Oblivion is a good game, but poor compared to Morrowind. Some of these mods are so tight that quality is improved while the poly count is cut to the bone, with very efficient sculpting and skins.

Quantity is something games designers used to overlook. Add enough of those mods and quantity becomes your new quality. Look for mods that reduce the poly count of grasses and background items while not sacrificing quality. Oblivion has high poly count backgrounds that are very inefficient. Most Oblivion mods I run are those that reduce textures. I fnd that even the highly recommended 'essential' mods packs can cause problems when stacked. I find that you want to have as few mods running as possible, less glitches that way.
