Looking for quality muscle rather than quantity of muscle if you know what I mean.
This means nothing - you can't build good muscle or bad muscle! you can only build muscle. I presume what you mean by this is that you would rather have smaller muscles and look leaner, than have bigger muscles and carry a bit of fat with them? This will come down to diet, not routine. I'm no diet expert so post in the Diet section and they'll sort you out.
As for routines, the great Gregg Valentino (lol) says here
, and most people would agree, that you should just listen to your body, rather than just following some set routine that you heard is supposed to be good that may not necessarily fit you. A routine is common sense really, I mean if you are hitting each muscle group once a week, and giving each group plenty of time to recover, then your gains will come, as long as you've nailed your diet. But there is no one perfect routine, most routines will get you results, be it a Push/Pull, Upper/Lower, Full Body, 5 Day or any other kind of split, its not going to matter THAT much, as long as you are getting enough rest time and you are eating well.
You should know instantly if a routine isn't right for you, because all a routine is is a means of maximising hypertrophy to fit your daily lifestyle. If it doesn't fit your lifestyle, you will know automatically. Otherwise any of the common routines you find people talking about here will do the trick, its just down to which one you enjoy doing most, as this is the one factor that will keep you motivated to go to the gym at all.
