A 
vortex for a single owner operator is a good move.........
I have raised my bottom line the day I got it and put it out on the asphalt and parked the 
CDS.. 
When I maxed out the 
CDS  I was going to get another truck and hire some one...
It was not a choice that I wanted to make but I seen no  other option.
Once I got into the 
Vortex I  can't max it out on my own and so I can't  see a reason to hire anyone
This has saved me alot of head aches.
I just sold the 
CDS   a few days before Xmas  It should be up in Kansas by now.
The 
Vortex cleans just as good as any decent  piece of equipment out there...  But weather you single and/ or  duel wand...........there are a lot of different benefits....
Now....would I start out of the gate with the all mighty 
Vortex.......
No.........  weather it be a PTO or a slide in  work your way up..
Like I stated above.I maxed out the 
CDS first..........
oh yea.........to answer the question about is it the best..
No ........... and I cant think of one that is......................
