Personally, I think Eddie had put in much much more effort in this forum and answer everything in a much more professional way. The other just come in once in a while to advertise.
Don't know, maybe just me or you guys see this as well.
If I were to buy wheels(considering that both company are equal) I would feel a lot better dealing with Eddie

Eddie is helpful, knowledgeable and answers a lot of questions here. Tirerack has good service and sponsors this forum.
Gary is a bit less friendly/talkative/"gee how's it going" type of guy, but he also knows his stuff. And Ronal sponsors all the Audi Club events.
