We FT and are in our second Excel-we have been in this one nearly a year. When we were shopping for this one, we narrowed our short list down to three, Hitchhiker (was still being built when we were shopping), MS, and another Excel.
We thought all three were well built rigs, made to stand up to FT rigor. There ended up being two things that pushed us over the edge for another Excel. First, a floor plan that we both we really liked, (and after a year, both really love). And second, we knew what the customer service was like with PI, and really didn't feel we could ever get better than they provide.
With that being said, we had not experienced any customer service with the other two manufacturers, so it may be entirely as good. I do think with MS or Excel you will be happy, so I probably would let the floor plan be the deciding factor.
