Oh, dear - can't narrow it down that much! In knit, I like cables. I like lace. I like knit/purl texture patterns. I like colorwork (almost all of it!). I like garter stitch. I like stocking stitch. I pretty much like any stitch!!
About the only thing I don't like is using slip stitch to create colour work. Like, where you knit a row with one colour, then use the second colour but slip some of the stitches on the first row, then use the first colour again but slip the stitches done in the second row/colour... I can't think of a pattern example at the moment, because I avoid them, lol... I'm also not fond of duplicate stitch for creating pictures on knitting...
I don't mind some of the slip stitch patterns for texture, where you only use the one colour of yarn.
In crochet, I guess I'm the same way - I like them all!! I like the basic stitches, I like the shells, I like the V stitches, I like the bobbles and popcorns and clusters. I even like Tunisian crochet!
