Here's one way to look at it: my wife, 14 year-old, and I all love swim-throughs. All of us have had many dives at Devil's Throat. We won't object the next time others on the boat want to go. If it's up to us, we'll go somewhere else. It's interesting, but the depth makes for a short dive. There are other spots that are, to me, much more spectacular visually - I'm a Columbia Deep guy, personally. There are other spots with many more interesting swim-throughs that are also shallower and thus longer dives. There are other spots with more critters and coral.
If you want a deep swim-through, I'll go for Maracaibo over Garganta del Diablo any time. It's more visually interesting (the famous "arch" is stunning), there's more to see in the way of sea-life (including a splendid toadfish that lives near the opening to the arch, and it's less crowded with other divers. It's still a fairly short dive, though, and there's a real risk of incurring a deco obligation if you're not careful. It's better as a planned-deco dive.
