and accessory lens options would be greatly appreciated.
This may be a very important factor for you.
You should consider the cost of 'accessory lens options' before you choose a housing. Some housings will be ready for 67m wet mate lenses. Other housings will require some type of adapter; that adapter could be expensive, might not exist, might not be satisfactory. And this may vary among camera models from the same housing manufacturer.
For the majority of housings, cameras get ruined by humans, very rarely due to a fault of the housing. (Human error, lack of maintenance, you loan it to a friend....)
So it is ergonomics and total camera system cost that are most important to me.
Cost is system cost. If a diver purchases a less expensive housing but has to spend a lot more money for an adapter for a wet-mate lens, the diver may have spent more on the camera system than if he had purchased the more expensive housing. (Plus may have reduced ergonomics simultaneously with spending more money.)
For example, most of the Canon housings (WP-DC##), and Sony housings, will not directly take a wet-mate lens. They are compact and reliable housings, attractively priced, but if you know you are going to be adding wide angle or close-up lenses, you should expect to pay more for for the system, than an Ikelite. Many Ikelite have 67mm threads on the ports. Many of the housings for point-n-shoot cameras are too small for 67mm thread, but Ikelite 67mm adaptors are very modestly priced. Olympus housings for their compact cameras very often have 67mm threaded mounts.
Ergonomics can be very negatively affected by adaptors. For too many of the clear plastic camera-branded housings, the only mounts available have to mount to the tripod mount on the bottom of the housing. Attaching the adpator there can cause great complications when you desire to add a camera tray. An example is here.
If you will ever be using strobes, consider how the fiber optic cables will attach. Many housings have built-in receptacles for "Sea and Sea" style fiber optic cables. If the housing does not provide for direct attachment of fiber optic cables, there are inexpensive fiber optic mounts, but these can be aesthetic disasters and might not meet your standards for reliability.
