This is a rather hard question to answer. Why? Well, simply, because there’s so much choice. Ultimately, it will come down to your personal preference. I know people who use a variety of different software. It’s to be expected, after all. Personally, I use Maya. I’m more comfortable using it, rather than Blender or , for example.
The same could be said for zBrush, Mudbox and so forth. It really comes down to what’s available to you (and what you can afford) and what works best for your pipeline. Most of them have trials. So, assuming the price isn’t an issue, you could download most and take them for a run. Find what works for you. Not everyone is the same. It’s really that simple.
