Well, I can understand that. The EAS is likely more expensive in the long run and certainly more frustrating, but the coils aren't perfect either (read up and you'll hear of some frustrations) and the initial costs of the coils are high.
I have had my LR3 for almost 13 years now. In that time, sure I've replaced some compressors but the AMK is said to be much better than the prior (Hitachi) and I've changed both air shocks in front (first one went out, second one I did voluntarily). As for the rears, they are fine. I don't know when I will change them but I can spread that out a bit, mostly because I don't drive it much so if I do the right rear next year I can wait another year to do the left and only ~2500 miles would have been driven so they wouldn't be "mis-matched" shocks or anything weird like that. Hmmm....what else? I have had a calibration issue because of complications with the failed shock on a trail (upper control arm was wacking the shock and also caused a bending of the sensor bracket) but a lot of these things were self-inflicted by not understanding what was happening under the rig when I heard it or felt it or saw it. There is a lot less to fear now, with EAS simply because we, as a community, understand it better.
As for articulation....I don't know who said what to you about that. EAS is not going to flex like a Defender's solid axles....but it does pretty well and I'd say remarkably well for being an indy suspension at heart. My statement was only that it offers more articulation than the coils, and that is irrefutable.
I will let this photo speak for itself...not flexing like a tricked out Jeep or Defender with a 1,000,000 RTI score, but you'd swear there was a solid axle under there, but no...that's the cross-link valves at work!
