I'll have to repeat what others have said, there is no one "best" method. What's best is what works for you. I tend to subscribe to the Howard Hill/Byron Ferguson method of shooting. I see the arrow in my lower peripheral vision and align it with the target. Hill was quoted as saying that he had "seen a lot of instinctive shooters but never seen a good one". I have to admit that nowadays I often don't remember seeing the arrow. The same holds true when I shoot combat handgun. I know I see the front sight but I don't remember doing so. It has all become an automatic process.
I started off shooting split finger, changed to three-under, and eventually changed back to split. My avatar photo shows me back when I shot three-under. Three-under brought the arrow closer to my eye level. This helped me see the arrow and aid in alignment. It never felt completely comfortable or natural however. Later on I experimented with split finger again and found I shot just as accurately. Not that I'm any champion shooter, mind you. I think the whole shooting process had become automatic by that point though.
As for other tips, here are a couple. First, don't overbow yourself. If you can't come to full draw and hold it for at least three seconds without shaking, you are overbowed. Learn to shoot before you start increasing the poundage. Second, and this one was really hard for me to learn, don't shoot too many arrows in a given period of time. Spread out the shots you make timewise. I was once the Master of the Empty the Quiver Quickly Technique. I was the archery equivalent of a machine gunner. My shooting wasn't getting any better and I couldn't understand why. As a matter of fact, my shooting got worse. The why was because my concentration would slip as my muscles grew tired. I was having so much fun that I'd just keep shooting though. Now I usually shoot one arrow, walk to the target and pull it, pet the dog, walk back to wherever I'm going to shoot from next, etc. You get the idea. Howard Hill was known to keep a bucket of arrows at the door to his shop and another by the back door to his house. Every time he walked from one to the other, he stopped and shot a single arrow.
Finally, don't get frustrated and quit. Trad archery is about accepting limitations. My max range with my flintlock is about 75 yards. I was once confident with a compound out to 40 yards. My max hunting range with a trad bow is 20 yards and the closer than that the better.
