Who plays any of those games for the combat? Morrowind might be the least rewarding given the early RNG whiffs, but in the end, they're effectively identical given your weapon simple slides across the enemy like thin air, and a number is assigned for the damage total.
Elder Scrolls are best for the adventure, and adventure hasn't been done well in the series since Morrowind., and I think anyone in it for that could look past the dated mechanics and appreciate the sheer flexibility and possibility Morrowind allows.
