Onescot, The reason EBC made my top 10 list is it the most scenic and beautiful hike I have done (especially when combined with the Cho-la pass and Gokyo). I was not that bothered about the base camp itself (other than it being a sort of end point/furthest point of the trek). Other people really enjoy being there "amongst" all the real climbers (I say "amongst" because technically you're not allowed into the actual campsites to interact with the real climbers in case you spread any illnesses).
From the base camp Everest is completely eclipsed by other mountains, but hiking to the top of Kala Patar (the highest point on a standard EBC hike) to watch the sun rise behind Everest is an amazing experience and the views of Everest from the Gokyo valley are even better.
For me it was the beauty of the hike that stuck with me although getting to the top of Kala Patar did give me a sense of achievement but it was more like a small summit within the bigger hike.
For a hike that offers a real sense of achievement maybe try Kili, getting to the top of that beast provides an amazing feeling, that was a hike where reaching the top really is the highlight!
Hope that helps - I would really recommend EBC (but add a few days for Gokyo)
