The 2 main styles are;
1. Full Harness and wing (SMS 100, 75, Nomad HOG etc)
2. Webbing Harness and wing (stealth, Z system, razor)
Generally the full rigs are for cold water and steel tanks while the webbing systems are more popular in warm water locals.
I have to disagree with this statement.... yes, there are two different types, but i wouldn't suggest that the webbing harness systems are more popular in warm water locations. I dive in the UK, coldwater, drysuit, steel cylinders and dive the Xdeep Stealth, it performs excellently and handles stages etc too with no problem.
It's very light for travel, low profile and infinitely adjustable, so is a great option if you will dive drysuit and/or wetsuit at different times, and is very easy to dive.
My diving, like yours, is primarily open water, wrecks, I typically dive to around 50m (150') and if i were buying again, i'd definitely buy the Xdeep again. They've recently added the Tec Wing, which looks excellent too.
Your decision may be heavily influenced by the people you dive with and the cylinder sizes you typically use. Here in the UK, it's "standard" to use 2 x LP85's (we call them 12L) but i understand that your side of the pond sometimes use the larger and heavier LP120's, in which case, you "may" need more lift? (I'm not certain of this, but it would be worth checking out)
The SMS range, i consider to be too bulky, but understand they are popular in the Florida region, but to be honest, that really is it's main fanbase.... once you get outside of the US.... i see mostly webbing harness based systems in use, the Xdeep Stealth, the Razor and the Diamond. Apeks have just released a brand new one too that looks nice, but i haven't heard any real world feedback as yet.
For the diving you're suggesting you are or want to do, i'd recommend a webbing harness based system, they are designed to be flexible sidemount systems, rather than hybrid systems that also support backmount..... IMHO... Jack of all trades, master of none, springs to mind for the big BCD based systems such as SMS.
