@Stuartbell The best approach is to find a surgeon that you feel you can work with and let that surgeon dictate the prosthesis based on your own medical situation. Surgeons will use the implant they are most familiar with given your lifestyle.
Hello Stuart, welcome to BoneSmart. Well done for reading up and studying, this is a Big Thing you're thinking about. I would treat all results like this with extreme caution. I'd also suggest that it's the skill and experience of the surgeon that counts more than choice of prosthetic.
