Here's the link to Dr. Clavell's video comparison. After I consulted with Dr. Clavell, he asked me if I had a particular implant in mind. I told him I had watched his video and could see the pros and cons of both, but I would rely on his experience to help me decide. After looking at me, he recommended the AMS, and that's what I was leaning towards anyway. I know that my penis will spend 99.9999% of the rest of my life not 'deployed'. During that time I don't want to think about it, and the pros of the AMS seemed more important to me. I know that's not the case for everyone, and I also know that Dr. Clavell implanted a Titan the same day he did my AMS.
I don't personally believe that a reputable doctor uses one over the other to keep their supplier happy. I do believe that one implant is nearly $1000 more expensive than the other, and that could play a role in which implant the doctor chooses when the studies show both options are generally the same in terms of outcome and satisfaction. I'm not aware of any doctors that adjust their fee based on what implant you choose, so the less expensive one would generate more income. If a high volume surgeon is doing 200 per year, and keeping $1000 more on each implant....well, that pays for the Lambo.
At first I too was very interested in the LGX because of the claim that it'll grow in both directions. I researched that claim and found that the length growth is minimal, and because of it's design it is the least rigid of the two AMS products. The CX is nearly as rigid as the Titan in longer lengths, and even more rigid than the Titan in smaller lengths, but you don't get the dog ears and crinkles. For me and my research, the CX was the sweet spot. I'm happy Dr. Clavell suggested the CX for my application, I'm just over 3 weeks post op and can tell that my wife and I will be very happy. I've read that many men have to back off a little bit because the rigidity can be too much for their partner, so it seems that both products are able to be more rigid than is necessary, which may make a rigidity argument moot.
Failures will happen with both (all) manmade products.
This may also be of interest, and 2020 comparison study. There are interesting results from studies in the body of the report, but here is the conclusion:
"Inflatable penile prostheses have been used successfully for ED not responsive to less invasive therapy. Both the AMS 700TM series and the Coloplast Titan® have three components, infection prevention mechanisms, and valves that make deflation easier for the user as well as prevent auto-inflation. We found little substantial difference between the two types of IPPs, with studies showing inconsistent minor superiority of one over the other. We recommend surgeons use their own clinical judgment and preference when choosing the right IPPs to use. Preoperative expectations may play an important role and further research controlling for this variable is necessary. Lastly, prospective randomized multicenter trials may ultimately determine the ideal prostheses for specific patients."
