As I'm looking into RIPs I'm finding it extremely difficult to get them all on the same page. I'm sure everyone here has been there, and you all have done a huge amount of research on the topic. So I thought a thread without any restrictions as far as an original poster's needs and purpose would be insightful.
So, which RIP did you choose, and why did you do so? Since choosing, what secrets have you discovered that would have contributed to your choice? Have your priorities (or your perception of them) changed since you made your decision?
If you've used multiple RIPs, by all means, comparisons of features and lack thereof are welcome.
