It depends on the image. With Lightroom, I've gotten the best results when shooting with two stop intervals. This was a LR HDR (I also tried it in HDR Efex Pro 2, but I find it much harder to get natural results with that, and while sometimes I like the more stylized HDR looks, a natural approach is better for my taste). The key to remember is that the resulting image is a DNG, so you can push or pull it much like you already would any other RAW file. By default it bumps exposure then pulls down highlights, but you may get better results by pulling down the exposure and then selectively bringing exposure up in the shadow areas with the brush/circle/grad filter selection tools. Because it's a 32 bit DNG, you can use those tools with pretty major exposure swings with minimal detriment to the image.
Also, pushing the contrast slider and choosing the Medium Contrast curve can give you a bit more of the punch back. In my image, I didn't want the foreground to actually be very well lit...I wanted a bit of that 'almost silhouette, but not quite' look, so I pulled the shadows back down (even though my bright exposure easily had enough detail to fully bring that up).
The A7 series has so much DR, that I can actually get quite close to the final image posted above just from the middle image RAW, but it lacks a bit of the depth and the raised shadows have considerably more noise.
