I've owned both the FAPC and Banshee and I preferred the Banshee. It sat in a more comfortable position for me, and the internal MOLLE was awesome. The Banshee is not as overbuilt as the FAPC, so it weighs a bit less as well. The only reason I ditched it was I was building a SEAL kit and it's not kosher for that.
If I had to buy another plate carrier for whatever reason. I'd get another Eagle Plate Carrier (I'm on my 3rd one. I keep buying and selling the damn things...). They're built stupid tough and work for any US military impression along with loads of other foreign impressions (SOTG, IDF, SAS and I think I've seen Italian commandos using them as well). The only real downside with them, is finding a place that has them in stock.
