I haven't really compared Cubase with other programs for a long while, so maybe I can't answer the question so directly. But I agree with Ramawes that Cubase is not really hard to use. It's set up like a tape recorder and you can just use it like one. Cubase is very deep in features, but you don't have to use them.
But having said that, there are a few things you should know first even to use it in the simplest way. You should read these parts in the manual, which may take you an hour or maybe a little more. Fortunately, the manual is great. You'll have to read about how to get the sound coming into Cubase so you can monitor and record it. It's not hard, but sometimes I find myself scratching my head trying to figure out why I'm not getting any sound coming in. (I do the same thing with my analog mixer, though.)
And there are other little things that are good to know even for simple recording. For example, when you record a take and you don't like it, you probably want to delete the whole thing. If you just hit delete, you'll delete the "part" from the screen and the song, but the actual sound file will not be deleted from the disk. To delete the part, including the sound file, you need to use CTRL-delete.
I think the power you get with Cubase is well worth the trouble to learn how to use it. But then again, I enjoy learning and using software while many people do not. I have heard that Cakewalk is a little easier to learn. But at the time I chose Cubase over Cakewalk (a long time ago), Cubase was clearly the better program. To me, a learning curve is not so important because that's only a temporary situation.
