I know this is an old topic, but I read through it all and found some very interesting viewpoints and I thought I would add a few of my own.
I used to use whatever ball I found on the course or on sale. I didn't have the game to have it make much difference. Then I started noticing that the feel of the ball was much different on different balls so I started using balls that felt good. Once I started to get a little control over my shots I realized that I could benefit from using a ball that was geared too my game. I saw a lot of high handicappers with low swing speeds using high compression premium balls because someone told them they were the longest off the tee. This is a mistake a lot of people make.
I did a LOT of research (probably too much) on what ball would be best for ME. Distance being probably the least important thing. If you are buying a ball because it goes farther than the rest you are probably missing out on a lot of what is important in making the choice.
For ME these are the five deciding factors of why I chose my ball in order of importance. Your mileage might vary but this is my 2 cents.
1) Color. I know it sounds stupid but my eyes are getting worse and with a white ball about 30% of my tee shots I don't even see where it went. I was losing balls on the course on shots that felt good to me. There is nothing worse than hitting a ball you think is in the middle of the fairway and never finding it. White balls are no longer an option for me.
2) Spin on the greens. I had a problem with my balls rolling over the green a lot. Even with my wedges. Using a ball with a premium cover was a HUGE help for me.
3) Feel off the irons (and putter). Some balls just feel mushy or like I'm hitting a rock. A ball that feels better to you will preform better.
4) Dispersion. I usually hit pretty straight off the tee but the difference of just off the fairway and just on is huge on the desert courses here in Arizona.
5) Distance. I don't feel I lose many strokes if my tee shot is a few yards shorter, but I really didn't have to sacrifice this much because I found a 70 compression ball that is matched pretty good to my swing speed.
My choice in the end was the Srixon Q-Star Tour. It checks all the boxes for me and I really can tell the difference.
I guess my point is there is more to consider when choosing a ball than distance and no website is going to tell you what ball will work the best for you. We all have to figure that out for ourselves.
