Very recently I bought my first BCD - SP Hydros Pro. As a beginner I am constantly working on improving my trim. Up until my purchase I have only dived with rental jacket style BCDs. In my opinion wings and back-inflate BCs help a lot with the position in the water. I'm sure someone with a lot of experience can go just fine in a jacket, but with a back inflate it is much easier. I am very happy with my Hydros so far and I can totally recommend it. It is light and packs really nicely for travelling. It also has trim pockets at the back. I moved some weight there and that also helped a lot. I'm not sure how well it will fit if you dive with a dry suit though. Maybe someone who has such experience can give you more information.
