I posted a similar thread asking this yesterday, I got about 20 replies that all said buy it.
I bought it and within 2 hours of playing I was instantly satisfied. You get a new island about the size of Whiterun Hold (The centre of the map, not the city) with a whole new look because Solstheim is in Morrowind. New clothes/armour/weapons/potions/spells/enemies.
I would strongly recommend buying this because unlike Twylightguard this is actually a big add on that adds lots of new stuff.
Ok, i'll buy it next week, together with Hearthfire...
