The big porty would be helpful whenever you may need to fully flush a larger area of carpet. Aside from that, a smaller porty could serve you well.

I agree though that the lion's share of your work can be done with your VLM equipment. VLM methods (based on encap chemistry) are becoming more prominent in our industry. And I'm confident that the low moisture methods will continue to grow as we move forward. It just makes sense.
