Dometic v.s. Duo-Therm Hard Start Kit - yikes, help....

I've read postings from folks who have added the dometic, duo-therm, or supco start kit and found it got the compressor started without a problem running same size genny or even smaller (honda 2000). I am definitely thinking of ordering one to give it a try; just trying to figure out which has been fielded tested as being the most appropriate.
I have a feeling from some prior insight from Chris Bryant mentions Duotherm as being a stronger option.
cheers
