How Important is Blender to You?? (Patreon)

So, as I've been practicing zBrush every day for a week now, and I'm beginning to understand why it's the number one sculpting software. This led me to a very important question I think we should seriously address here in our community:

At what point do you think we should consider adopting another software over Blender?
My reason for asking is because I have been keeping an eye on Blender's competition, and I'm quite impressed with the how fast they are catching up. Blender's biggest strength is it's price. But, the most ironic thing I've found is that almost all of the best Add-Ons for Blender cost money, sometimes going from $50-$100. At which point, often invalidates the point of using Blender in the first place, because for prices like that, you could be using paid software that would do a better job.
