I can do both and find they are both easy - of course, it takes practice, like anything else. I learned in the '60s and even though I didn't knit for over 25 years found it very easy when I started again last year. The same with crochet - I didn't do it for over 10 years but had no problem doing it again in the past year.
Practice, practice, practice!!!
