Yes, I can confirm that once you had a 3 axis system, there is no way back.
I started with an SRP-230, the three axis 'platform' you can hook under your existing 2-to-3-seater sofa. I had the impression, though, that having my feet on the ground (as with my legacy sofa and the SRP-230), the effect, especially from the movements (in contrast to vibrations), wasn't as authentic as it possibly could be. I also had contacted a manufacturer of sofas with recliner mechanisms, but when I told them about movement and vibrations, they were in doubt whether their reclining mechanism could cope with it.
Then I got the opportunity to acquire a loveseat at a very reasonable price. Sitting on the 2 axis loveseat and having the feet off the ground, movement was really cool. I noticed, however, that all the motion was originating from behind, which felt weird, being used to feel the 3 axis motion. So I did the 2D-to-3D upgrade for my loveseat as Yannick mentioned.
Therefore, from my experience, I would always recommend a 3 axis system with a recliner.
Hope this helps.
