Yeah QD Inventory is a suitable holdover to use for now until SkyUI or you could use the older 2.2 SkyUI with some of it's limitations like in the crafting.
From everything I read and saw about ESO at launch it was pretty bad. Over the weekend Steam had a 5 day free trial of it which I think might still be on for another day, not sure though. But it is still on sale for 50% off the Gold Edition which is worth buying cause you get 4 of the DLC packs (which include the Dark Brotherhood, Thieves Guild and 2 others) and a mount.
All I can say about the game is for the last few days I have been playing it I have been having a lot of fun playing a Khajit NIghtblade doing the Thieves Guild and Dark Brotherhood quests. I have no idea what the end game will be like but having an optional monthly subscription is a good thing. I choose right now not to pay the sub and I am not locked out of any of the content except for a couple of DLCs for content I wouldn't even be doing right now anyways. The game world is quite large, the cities are huge and look fantastic, the game play is great. It looks and runs better than Skyrim, it is extremely stable and as far as I am concerned for 40$ even if I just play through what's available to me it's money well spent. I wouldn't want to pay the full 80$ Canadian for the Gold Edition however. I like their pricing model, it offers good flexibility to the player. Buy the game and skip out on the monthly fee if you choose or subscribe if you want the extra perks (10% gold and xp and DLC access while subbed) and build up crowns (the cash shop currency) to buy future DLCs or cosmetic bullshit.
I can only give it my 2 thumbs up in approval of what I have experienced in the game so far.
