I'm not in sales, however in my current role I get to talk to a lot of sales people and it seems that most of them don't (and don't have time to) use any fancy tools at all, especially the successful ones.

Also the last two companies I worked with were in the process of switching from SF to MS Dynamics. Not exactly sure to why, but seemed like one of those cases where the people at the top made the 'deal' and later people who actually had to use realized it didn't work for them.
