Oblivion's map is better. Oblivion's journal is much better. Oblivion's UI is better (never thought I'd have to say that, ever, in regards to another Elder Scrolls game :shakehead: ). Oblivion's magic is better. Oblivion's quests are better. Oblivion's faction questlines might be better.
Skyrim's world is much better. Skyrim's dungeons are much better. Skyrim's AI might be better. Skyrim's main quest is better. Skyrim's political backdrop is better. Skyrim's enemies seem better, but there are much less of them.
Skyrim's a great game and all, and I love it, but I think people demonise Oblivion a bit too much. I have very fond memories of Oblivion, and I can say without nostalgia clouding my judgement that I prefer some aspects of Oblivion to those we find in Skyrim.
as previously stated, i hated oblivions UI way to choppy on a console vs the PC. ill make my personal comparison.
oblivions compass was tiny and stuck in an odd plae on the screen, got used to it but after seeing how skyrim incorporates it into the enemy health system skyrim wins for me
inventory was alright in oblivion, i cant say it was bad, but i like this new system more, same sub-menus for items (weaps, armor, potions, etc) and it still gives the same info on items on the right. i havent had a problem with sorting in skyrim since the carrying capacity is more toned down to 300-400 on most rogue / mage classes and since everyting is alphabetical and not just randomly thrown in to where i have to sort it, i can find it easily with no hassel.
Im not getting into magic, for i have a very strong opinion about it.
eh faction quests are dull on both ends. skyrim at least gives us somthing to do once we become guild master, we can continue to do menial tasks etc
Quests is general though skyrim has oblivion beat by a mile. oblivion has a lot of fetch quests having you run from city to city, you get some variety but nothing too interesting to blow your mind. Skyrim divides the misc tasks and main objectives rather nicely.
fetch quests are delt seperatly while main quests appear in the journal. skyrims quests have alot more depth to them some lasting mere minutes while some having long chains.
oblivions journal felt cluttered instead of naming the quests they were logs in a journal that you had to skim to really remember what quest you wanted to do. Skyrim as said presents it more available to the player easily and less time in menus and more time in the field
you could argue story, UI, graphics, AI, Combat, anything all day, but in the end they are two completely different games made seperate from each other, its like comparing apples to oranges
