The sleep on the EEE is great. Kicks in quickly (I believe you can set the exact time), conserves power very well and starts up immediately.
As you know, the EE hibernates but even left hibernating, will be dead if you try to wake it up the next day if it hasn't been charging. Not so with the EEE. Battery life/consumption is amazing if your standard is the EE. It won't be a disappointment!
As for the screen, the EE screen has better contrast. You need to be in pretty good lighting to see the EEE screen well; it just seems more muted. The other slight issue can be if for example you have a bedside reading light. The EE only needs light, and glare is pretty much never an issue. But the EEE, I guess being an LCD, can still be subject to glare. So you need light, but also well-placed light. (Unlike the EE where glare doesn't seem to be an issue.) So when you combine the lower contrast with perhaps fiddling with the light source, reading on the EE is a better visual experience.
I don't often experience much lag even writing on the EE, but the EEE is even smoother/faster and I find the pen tools can be controlled with slightly better precision, even if your annotation options may be a bit more limited. So the actual physical writing experience, taking notes etc. is just as good on the EEE, maybe even better than the EE.
As I've written earlier, though, *using* what you've written is a bit more of a pain on the EEE if you want anything more than a graphic file uploaded to evernote. So the best use of the EEE is still, I think, as a kind of spiral bound notebook replacement. If you want to keep everything contained on that device, have all your notes in one place, have things available to read and a few games to play but mostly think of this as your scratch pad, "book of sketches/ideas", source of infinite sudoku puzzles etc. you'd be very pleased with the EEE.
I find that the EEE is my *first* choice for picking up to quickly jot something down. I have several devices on which I could do this, but battery life/wake from sleep time leave something to be desired on everything else: Nokia N810, Edge and old tablet PC. (If I had a dedicated office area where everything could be constantly plugged in, that would help. But I don't have such a space set up.) The EEE could be lying somewhere, unplugged, and it will generally still have good battery life remaining and resume quickly enough to use to jot down a phone number from a voice mail. It really is like an electronic notebook that way.
The EEE is my last choice for creating annotated PDFs for my curriculum site like the ones I posted earlier, not because of the writing experience, but because of the difficulty in turning that work back into quality pdfs, and the lack of zoom/colour options.
And you couldn't possibly be faulted for not reading my past posts in their entirety!
