What after NX2? Or stick with it?

Nx2 has some advantages over LR when using control points and / or Nik effects: It does not have to make a Tiff. I do like LR and NX2. Its a bit of a toss up. One can get similar results with both programs. If Lr gets you nearer to what you want without too many manipulations go for that: otherwise NX2. The 64 bit version of nik effects for capture Nx is available. Latest version of view nx (2.5) seems pretty fast for browsing.
