Dear Rachel,
Yes, I have had a similar experience. I signed on with Uwe Stender in July. He was not the only agent expressing interest in my manuscript, but I was most impressed with his honesty and enthusiasm, so I chose to "go with my gut" and choose TriadaUS. I did so being fully aware, as you should be, that Uwe has had success in placing non-fiction but has not yet sold a fiction manuscript.
I can tell you that, so far, my gut instinct has been correct. Uwe is honest, hard-working and always prompt to reply . I have been kept apprised, every step of the way, of where my manuscript has been submitted, who has responded, and what they had to say about it. It has been my understanding that some better-known agents can be harder to get in touch with and are less forthcoming with this information. That may work for some writers, but personally, it would drive me nuts. Your mileage may vary.
As to whether you will "soon" be published, you do need to be realistic. Getting an agent is a big step, and one you should celebrate. But it's just that...a step. It's still another giant step to get your manuscript published. No agent should promise that they can get you published. They should only vow to try.
I believe Uwe is trying his best for me. I'm not yet published, but it's still early days. I wish you much luck, and I hope you choose the agent who is right for you. And I hope sharing my experience with Uwe will be helpful to you.
Best of luck,
