I feel your pain. I like and still use NX 2, particularly for an image that I want to print. I bought the Nik Color Efex 3.0 a long time ago, too and really like it. As you know, Nik's plug ins are available for Photoshop, LR and Aperture. The U-point technology and other features are similar to using NX 2.
One nice think about the Nik plug ins for Aperture and Lightroom is that they work with both. So you could try both with the Nik plug ins and see which you like better. Good luck. I think the near future will be a time of software uncertainty.
