Can only speak to Bonaire. If we knew what resort you were staying at, we might could comment on the house reef. Now, of the general west coast sites, roughly north to south, focusing on those that are 'distinctive' and well-recognized:
Karpata - more lush reef than some other sites.
Karpata requires you to hit the 1 way portion of the road, committing you to a long round-about trip home, so also hit Ol'Blue (Tolo), a nice overall dive with good entry/exit, that's also up that way, when you head for Karpata.
1,000 Steps - 60 somethings steps down & later up, yeah you feel the burn, but the stair case is scenic, it's a nice place for photos, and one of those sites that has strong name recognition.
Oil Slick Leap - it's a nice site where I've seen neat stuff and had fun dives, but this big giant stride where you drop probably 6 feet to hit the water is the signature aspect of it.
The Cliff - a shallow vertical wall. It's not so obvious where it's at off the main road; a bit north of Buddy Dive & Captain Don's Habitat.
The Hilma Hooker - you'll probably get 70 to 90 feet deep swinging around the wreck (look for tarpon on the far side of it), but it's perhaps the most recognized Bonaire dive site, a pretty big wreck and a chance to something big (tarpon) if you haven't seen anything at all big anywhere else. Dive does tend to run a bit deep; wouldn't make it my first dive of the day. Particularly if diving air rather than nitrox, watch your NDLs.
Windsock - nice shore dive with a very large wooden pier & easy entry/exit. I like it because I can go in & get out beside the pier, making where to come back & exit real obvious, even at night.
There are plenty of other good sites I like; Andrea I & II, Buddy's Reef, Angel City, Alice in Wonderland, Sweet Dreams...but the ones I listed (plus perhaps Salt Pier; though whether entry is allowed has been argued; I can tell you people dove there last August!) would give you an intro. to the mainstream sites, some of the ones people are most likely to ask 'Did you go to...'
