Which countries do you think travel advisors or agents are still useful?

I have stopped relying on travel agents for a while now as they added little value that I couldn't figure out. On top of that most of them had fixed itinerary that's very sterile. They funnel you to places that give them commission.

I recently came across some blog about Fora, HERA (for ACCOR) and stuff. I reached out to some of them just as a sanity check. That was a complete waste of time. Some of them were rude and hostile when I sent screenshots of same hotels with significantly lower prices on other websites.

So for places like US, Europe, Japan, Korea, New Zealand, Dubai it looks like travel agents are not really necessary.

For India, Egypt, it looks like they make sense.

Any other suggestions or experiences where they helped?

I have Thailand, Vietnam, Sri Lanka, China ok my list eventually.
