I am not super experienced. However, having been through two full sets of gear in less than two years, I can appreciate your doing the research before you buy. I purchased the majority of my gear right after certification. As I have gained experience, refined my diving skills and train for more advanced diving, I have found myself upgrading certain portions of my gear. My BC being one of those items.
If you plan on strictly recreational diving, then any number of BC's will work just fine. However, if you plan to later progrees into more advanced diving you may have to buy a new one better suited for that type of diving. BC's that can easliy be adapted for both are good choices if you are unsure which path you may take. Zeagle, Dive Rite and Apeks (just to name a few) all make BC models that can be adapted for both recreational and more advanced diving without having to purchase a whole new BC.
Gear selection is IMO largely a personal choice based on comfort, features, abilities, functionality, style (debatable) and price. Ultimately it comes down to deciding what's right for you based on your needs and abilities. If you can, try out a number of different BC's before you buy one.
You'll get a ton of responses from this board as there are advocates for just about every Brand/Type of gear out there on here.
