My xr650 has a no-toil on it, and I've always used either uni or twin air on everything else.
Except for the difference in cleaning they seem to perform the same. I bought the one for the xr as a tester, I haven't decided one way or the other which one I like better. Also I haven't had it long enough to comment about longevity.
The no toil is easier to clean. Either way its messy, but using water and a kitchen sink beats the parts washer and diesel fuel.
All typos and misspellings blamed on my phone.
