I can offer some insight about that question.
If I'm not mistaken, the Dorman is simply a rebranded Powerbond and both are basic stock replacements.
Innovators west is a performance oriented damper that will work fine for the street but it is quite an investment to make it work for the street. The #1 problem is the pulleys. The dimensions of the damper will place the crank pulley farther forward than stock. For all but possibly a T-Bird application, this requires shimming existing pulleys, finding aftermarket pulleys for other engines that fit or having custom pulleys made. Another issue is front engine mounts or steady rests may need to be clearanced. Another is that the damper is slightly larger in diameter, which requires that the timing pointer be adjusted or a new one made to fit. So all together, it is a good bit of time and / or money and it is probably not really worth it unless it is for a high performance street engine or race engine - this is where I'll defer to Ted.
For my install, a custom crank pulley was required because I could not find anything with a diameter that was sufficient for street use. I also opted for custom water pump and alternator pulleys, again due to diameter requirements, to make everything work well for the street, but also aesthetics and fan spacing..
