From your initial post it looks like overall you're better, Q-wise - I'd start with Low press/Zonal/Normal tackling. If you go attacking for any reason turn off counter and high press on, until they start taking long range shots then turn it off again. I only use hard tackling if I'm in defensive mode and they're still causing me problems - I don't know the difference discipline wise, as I used hard tackling as default for most of a season a few seasons ago and went 13 matches without a card. I've never had any success with man-to-man marking so can't advise from experience there.
