I love shore diving. I would guess that over 3/4 of the dives in my log book are shore dives . . . but that's because we have such good, easy shore diving here in Puget Sound. But my husband and I have gotten to where we rarely dive off a boat in Maui (where my in-laws used to live, so we went there often). Yes, the viz in Molokini is sometimes better than inshore, especially if the surf is up. But you see the same coral and the same critters. My only manta in Maui was in 20 feet of water at Ulua beach; two days later, we were buzzed by a whole pod of dolphins. We played with a monk seals on a shore dive in Lahaina, and the Mala Pier is still my all-time favorite Maui dive, and in the daytime, you can do it from shore.
I've done mind-blowing dives in Monterey from shore. I did dives on the house reef in Lembeh from shore that easily equaled what we did from the boats.
There are places you can't get to without a boat. They exist in Puget Sound. We've also done the Socorros, which are obligate boat diving, and the Brothers Islands in the Red Sea, which are the same. But I think you could spend a whole diving career diving from shore and still have a ball, see fascinating stuff, and not feel left out at all. (I have friends who get so seasick on a boat, I wonder why they don't just stick to shore diving!)
