Hassled,
One EA was very hands on for the first two weeks but when the property didnt sell as quickly as he had promised he seemed to loose interest very quickly, would't return calls etc., my friends eventually asked for a different person to deal with the sale and eventually got the house sold but only after a lot hassle on their part.
The other couple were swayed by talk of high prices, exclusive lists of people just dying to by their house and advertising blitzs, and went with the agent who promised them the sun moon and stars, several weeks later and very few viewings they asked the agent to drop the price (to a more realistic one IMO) and eventually they sold.
Both of these agents were recommened very highly to me by both couples and i got both to value my house along with another EA however after interviewing all three EAs and narrowing it down to two (one was a real flash git, ruled out within 5 mins.) was in a bit of a quandry as to who to pick. I went with the one I felt most comfortable with, seemed the most down to earth and truthful and I got lucky.
Good luck with whoever you choose.
