I'm going to go with NO. I spent a week diving in Isla about a year ago and for the most part was unimpressed. The sculpture museum is kinda okay, but really just a bunch of statues under water. Their reefs aren't bad, but are super shallow. I don't think you can do much diving there below 40' unless you dig a hole in the sand. There was a wreck dive that was cool, but it's a bit further out. There were some eagle rays that just seemed to hang motionless in a very strong current above the wreck. It was a bitc* getting down and back up due to the current. If you lost your grip on the anchor line you'd be long gone. The wreck itself is okay, but it was the eagle rays that really make the dive.
If you're used to diving in Coz, you'll think Isla is a snoozer. There is just no comparison.
