builders ask that question of us all the time....my answer is that the agent with the most subdivisions get the most calls.... people buy on comparison and they want to see it all... we promote our listings....all of them....

Mike - Meet with both and go with your gut instinct. What is most important is that your agent is someone you can trust, and you feel they will do a great job for you.

Neither...you interview several and pick the one that you feel will do a good job selling YOUR home

It may be smarter to list with the agent who has sold the most this year.

we show sellers our average days on the market compared to the MLS average.  We win. :)

I think it's important to meet with at least two Realtors. Make the time. Sometimes, the busiest Realtor has a team that is actually doing the work. It's impotant to find the Realtor that you feel comfortable with and trust.

Interview them all and list with the one that meets your needs

It depends on the agent, some agents cant even handle 1 listing. In my area there are some with the most who get them because of that thought and their franchise name. You cant reach them though, done count on them to answer their phone, return a call and forget email. If you are a home owner you may see their assistants but service, you will soon ask what is that. Pick the best agent who will be there through each step of the selling process and ask that up front. 

Do you trust the knowledge and expxrience of the agent is the question...there may be reasons why or why not they have lisiings.

Unfortunately most just use Ouija boards, or an unemployed relative to help them pick.

But the smart ones go to Active rain and learn who is good.

Which knows your area better and ask what kind of marketing each one will do.
