Any have any recommendations for a good corporate TA? Someone that actually knows more than I do?

My company insists that we use the company TA because they are supposed to check that we are flying within the rules (eg cheapest nonstop fare). The irony is that my company TA's website is so terrible that it often doesn't find the cheapest nonstop fare anyway (kayak does much better), so I have a pretty good case to get my company to switch if I actually know that there are other agents that can do better.
