I know how to do both, but I hate knitting English. For me, it's slow, my hand gets sore too quickly, gauge is off, and I end up dropping the yarn too much.
So, I knit Continental. I do not hold my yarn how all the knitting books suggest, as that also leads to hand fatigue. I wrap the yarn around my middle finger and use my index finger and thumb to manipulate it. Little movements keep my knitting going fast
