Regardless of it's technology golf will always be tougher to excel at than bowling.
Let's assume that your driver clubface is not perfectly square at impact, and only off by 1/8 inch. For an average golfer with only average swing speed the ball can be off target by 60 yards (in any direction)!! Bowling will never be so precise.
Having said that, I LOVE both sports! The average golf season where I live is about 7 months long. Bowling is whenever I want; cold, hot, windy, rain, snow, you name it. If I walk 18 holes I get some good exercise. I'd get much less if I only hit the middle of the fairway, but that's another topic. By comparison, if I bowled for 4 hours I'd also get plenty of exercise.
I don't get skin cancer from bowling... I don't eat pizza while golfing... The two are extremely fun and addicting, but to me they're way different.
