Zeagle is a brand, not a style of BC. All styles of BC have excellent models and poor models. Some prefer a vest, others prefer back inflate, some love BP/wing while a rare few won't give up their horse collars. All of the styles work quite well IF they are well designed. If they are poorly designed (quite common) they don't work nearly as well. I've used all styles of BCs. I've found excellent BCs in them all and poor ones in them all.
Two advantages of the BP/wing are: 1. you can fit it exactly to you regardless of your size and how are you are to fit. You can also change wings if you move to large doubles and need more lift.
Common myths:
Back inflate and BP/wings push you face down in the water.
You can only use doubles with a BP/wing (you can wear doubles with any BC as long as the BC has enough lift).
I'm much more concerned about how well a BC is designed than which particular style it may be.
Things to look for in a BC:
1. No padding - Padding requires additional weight, yet compresses at depth so it no longer cushions. Additionally, air in a BC lifts the BCs weight off your back rendering padding redundant. Padding also increases drag, making dives in current more difficult and increasing your air consumption.
2. No cummerbund - Cummerbunds increase drag.
3. Dump valve at the highest point of the BC. - Inflate the BC and hold it up as if you were wearing it at the surface. Is the dump valve at the highest point? If not, look for a different BC. If it is, turn it as if you were swimming in a prone position. Is there a dump valve at the highest point? A good BC will pass both tests. If the dump valve is not at the highest point, it will trap air, requiring contortions to dump all the air or additional lead. A nice extra is a right shoulder dump valve and dump valves at the bottom.
4. No fabric covering of the bladder. - These BCs are sometimes called "bladderless" or "single bladder BCs." The fabric covering creates drag in current.
