I've only used a few rolls of Ektar so far, and I'm sure I can get more out of it after learning.
However, I didn't find it difficult at all. I exposed it at box-speed, let the camera meter and received perfectly fine photos. They were more saturated than I'm used to from negative film, but I had no problems, and they were great.
That said, as I get better at metering (I know in theory, but practice is always different) and what Ektar lends itself best to it, the photos will only be better. Make sure the exposure is correct, but I'd not worry about it other than that.
