I've seen friends playing the new improved client, they have trouble opening their back packs, can't walk through gates, crash at the worst moments, lose stuff in their containers... and all this is improving?
I was fortunate in a way, I was away from UO for almost two years, and when I came back I figured the break was a good opportunity to try something new, because I was rusty with the 2D client as well. I'm glad I did.
I've had some issues with stability, and graphical glitches, and I have some movement issues due to some stupidity on the part of the enhanced client's design, but overall, it is much better than the 2D client.
It is more stable, especially when you run it in full screen mode. There are things you can do with it that you simply can't with the 2D client. I'll list a few.
1. Instant dress and equip. You can make macros that will instantly redress you with your full suit. It isn't like UOA where you redress one piece at a time, it is like what happens when you loot your corpse, it is instant. And if you have forgotten to change one piece in the macro, or left a piece behind, the macro won't get hung up and leave you half dressed. If you don't have a piece on you, it will simply ignore it and dress you with what you have on you. This is a bit of a two edged sword, but for the most part it is a good thing.
2. You move faster. As long as your ping isn't horrible movement is faster. You can move at top speed without the use of a cheat, and you are less affected by lag, and you move through obstacles in every direction without getting stuck (in the 2D client this only happens along one axis of movement). This advantage cannot be overstated in pvp.
3. Did I mention it is more stable? Since I switched to full screen I have yet to crash. I used to dread certain sounds in the 2D client, because it very often was the precursor to a crash (pet death sounds, and death sounds in general). I still cringe when I hear those sounds, but that is just from my years of playing the 2D client.
4. You have a fully up to date map on all facets and in every area.
5. Healers show themselves on your map automatically when you are dead, as does your corpse after you have been resurrected.
6. The UOA macro functionality has some advantages and can do some things that the Enhanced Client macro functionality can't do, but the Enhanced Client macro functionality can do some things that the UOA macro functionality can't, so it's a bit of a wash. You can actually insert one line scripts into macros.
7. Full widescreen screen support. The game play area is fully zoomable, and you can resize it to your hearts content.
8. Right click to loot items off corpses. No more clicking and dragging.
9. A much more powerful and flexible targeting system.
10. Moddable UI. I love mods. Well there are mods available now for the enhanced client. Different icons, different looks for your desktop. If you have the time and skills you can mod it to your hearts content, and if you don't, there are some very nice mods out there that should suit just about any mood when it comes to appearances and others that improve the functionality and usefulness of the UI.
These are just the advantages I can think of off the top of my head, I'm sure there are more. The KR client looked great for the most part, but it was buggy and unstable. This is
not the KR client. I gave up on the KR client and continued to use the 2D client, but if I was ever forced to go back to the 2D client now, there would be a very painful process of adjustment, and my game would be negatively affected.
There is another thing. If you are used to the 2D client, there is enough familiarity in the graphics and options that the enhanced client actually feels like the same game. The KR client was so different that it didn't feel like UO to me. One of the biggest bugaboos for me with the KR client was that you couldn't arrange items in containers, vendors especially, in the KR client so they could be viewed in the 2D client. The enhanced client doesn't have this problem. The legacy container mode works as it should and you will see the contents of containers in legacy mode the same as you would see them in the 2D client.
