Sunshine suites is not ocean front. Cobalt would be my choice. Reef divers will bring boat around to wherever there is a leeward shore so no worries about being blown out.
The concern with getting blown out at Cobalt Coast is not with the boat dives, but with the on-site shore diving that seems to be the only option they currently offer in the afternoons. ( I have gotten blown out there in April.)
I think CC would be all-around the nicest experience of the 3, but it may be more effort to maximize the diving, which DanG wants for a short trip. I think it's actually a pretty nice place, but doesn't come off as fancy because things are more of a modern Danish decor. IMO it's actually a great location for those who prefer "off the beaten path" - in a peaceful quiet area, but not really that far to civilization when you want it. (We've always rented a car.) You could hope for good shore diving conditions there for the afternoons. I didn't think the shore diving at CC was good enough that we wanted to do it much even when conditions were good - it's a longish swim to much of anything. The North wall is theoretically an option but it's a major swim, like a scooter is very useful. If shore diving there doesn't work out you could rent a car and hit the Sundivers at Turtle Reef and Divetech at Lighthouse sites nearby to dive for the afternoons, which is not a bad idea anyway as they're good sites and are usually a little more sheltered. Or arrange afternoon boats with another op if Cobalt still isn't doing anything like that - Stingray City, Kittawake, whatever.
I guess enough people like Sunset House, but I'm not a fan. It's been a long time since we stayed there last, and at least the rooms look nicer in the pictures than they used to be and they've made other physical improvements. But their boats were slow and crappy, they dove the crowded West end sites an awful lot, and the shore diving there seemed beat - I'm not sure any of that has changed. For a short trip where you want everything convenient and as much diving as you can get it could be a good option, but I'd just expect to get better dive quality elsewhere.
I haven't stayed at Sunshine Suites, but I think there's a pretty reasonable restaurant there, which I'm not sure we've ever managed to eat at because it's so popular and packed. There have been occasional discussions of affordable eats on this board which you could probably find. One place which always comes to mind is Chicken Chicken. If you have a car and some sort of kitchen, the grocery store in West Bay used to have a great selection of prepared foods.
You might also look at Compass Point/Ocean Frontiers on the East End. No shore diving there and not AI, but they have am and pm 2-tank boats and a few night boats. I'd expect good conditions in April and it gets you to some of the better diving on the island from there. You'll want a vehicle, but sometimes they offer room/dive/car packages that are pretty good. All around great place.
