Should I stick with these or are the better options that have come out in the past 6 months? You advice is greatly appreciated.
Efest is one of those re-wrappers that don't always use quality cells. They also rate their batteries at absolute maximum (burst current) instead of CDR (continuous discharge rate). So, you have to understand that when you buy Efest there may be wide variations in available capacity from cell to cell.
That said, I have several Efests that perform well for low watt vaping. You just can't use them for performance vaping at high wattage and expect to be safe.
Lots of vendors sell batteries at a premium. You are better off buying batteries from a supplier that sells batteries that are tested and proven to be what the label says. RTDVapor, Orbtronics, and Illumn are vendors who sell guaranteed quality cells that they test to perform as advertised. You will pay lower prices from those vendors and get guaranteed OEM batteries.
Take a look at Mooch's battery tests for an idea of the differences in battery performance.
