I didn't enjoy the original game at all and nearly forced myself to try the enhanced edition of it. And I was amazed that it felt almost like a completely different game. The game is fully voiced now. There are extra quests. The previous writing was refined. Companions now have serious backgrounds. The lore now feels very integral. The graphics was improved (although it was already good). The UI got refined. So, if you didn't enjoy the original game, I really really recommend trying Enhanced Edition. To me it felt like the best enhanced edition of any game I'd seen before.
