100%, undoubtedly, go for the Butterfly Amicus Prime. These are my reasons:1. Prime has a better ball-feed motor. (Butterfly upgraded theirs for the Prime). The 5000 has the same ball-feed motor as the generation 1 Amicus robots (basic, advance, professional).2. Prime looks totally cooler. No one wants a robot that has the word "pong" in it. They associate it with "robo-pong". They will take you much more seriously if you tell them you have a Butterfly Amicus.3. The support and warranty on the Amicus robots are much better than the warranty from Power Pong naturally because Butterfly is 10 times more developed than Power Pong. At least with Butterfly, you know that they have a legit customer service and distributors all over the world. Also, Larry Thoman- their Amicus robot repairer- is very competent. He has direct access to all the parts and responds very quickly by email. When I emailed Butterfly about their robot, they responded in a few hours. When I emailed Attila Malek of Power Pong, he took several days to respond.4. Amicus Prime comes with its own tablet (a first). On the tablet, they have their own app which transcends anything Power Pong has to offer. It even offers a "wait" function that senses your serve and then starts a drill. The Amicus Prime also has a mirror function at the touch of a button that can mirror any of their drills.5. The spin on the motors is crazy. Absolutely no way to return max topspin or max backspin. It is as simple as that.6. Timo Boll uses this robot.7. If you ever happen to take this robot on a plane trip, security is much more likely to recognize the brand Butterfly rather than Power-Pong. I had no trouble checking my robot in. 8. I just like the sound of "Butterfly Amicus Prime" rather than "Power Pong 5000".Sorry if my review is biased but I own a Butterfly Amicus Prime and I absolutely love it.
