Most manufacturers make, or have made for them their own
solution . These private labeled solutions are tested in their own booths and the booths are adjusted for that particular
solution viscosity.
It is possible to use other manufacturers solutions in your booth, but not always recommended. Some manufacturers will void your warranty if they know or find out that you have used another brand of
solution in their booth.
As to whom makes the better
solution . I can only recommend that you have to see which
solution provides you with the best results in your booth. Each manufacturer will tell you that their
solution (as well as their booth) is the best. The best choice is that which you have seen the best results and that which has the most satisfied customers.
