Either will work well. I get good flavor from both but a slightly better more pronounced taste with the 1.8 ohm coil. I just tested out a brand new 1.8 ohm coil with Razzleberry juice and hits solid. Coil lasts me seven to ten days on average. Good draw and flavor. Be sure to "push" the coil into the base, no screwing in like other coils on the market, these are very simply to use. I let the coils wick for about 3 minutes with the tank upright and take a few prime hits before mounting the tank on my APV. Good luck and enjoy...
