Well, I dug deep to educate myself in this research for all of the options out there, and my main factors are:
- the success rates
- lasting results
- maintaining sexual functions
- and the fact that my older brother is VERY pleased with his GreenLight experience ("pissing like a race horse").

Keep in mind that everyone is DIFFERENT with varying degrees of results, and that comparisons are opinions that can vary so much from man to man. Anyone can compare other forum posts out there and come up with completely different data. Not one procedure is "perfect" with a "one size fits all" approach. Also, prostates keep growing at different rates for every man, so retreatment is not out of the question for any one surgery.
