Bean source, processing, roasting profile, freshness, grind, temperature, and brewing method all play a part in making a good cup of coffee. And of course taste is subjective so it's hard to get an absolute answer here. Kona coffee is likely overpriced and overhyped. In my opinion there's a diminishing return on coffee taste past a certain point. I haven't seen any indications that the really expensive coffees' tastes are proportional to the price, it's just that demand is high because they're famous in some way (Kona, Blue Mountain, Kopi Luwak) For a real eye opener of "bean origin affects flavor", try some Ethiopian Yirgacheffe beans from a reputable roaster. You should get strong blueberry notes from the coffee, quite different from other regions' coffees. It'll be more expensive than a bag of whatever supermarket coffee, but there's a clear distinction in taste. Whether you like that taste is entirely another thing, but drink whatever tastes good to you!
