There are no factory coils that will last a long time. Just a fact sadly, and while some last a bit longer than others (week or two if barely used) it still comes down to the answer huckleberry gave. If you want something that lasts a long time, saves you money in the long run RDA and rtas are your best bet.
However there's one tank that's kinda in between. Its the horizontech krixus tank with rebuild able ceramic coils. Here all you have to do is dry burn the coil and rewick the cotton. Flavor is not bad but it takes at least a mod that can do 90 watt or that tank leaks like no tomorrow, as well as vape/flavor output would be mediocre. Tank itself gets very hot, so no chain vaping. Reason I mention this one is, the coils last around 3-4 months (6 is advertised but I've never gotten them to work that long) and its easier than RDA/RTA since you won't have to install or build own coils. Its cheaper than factory coils and has a longer life span. Its above average on flavor in comparison to regular tanks but would lose that battle if compared with RDA/RDTA/RTA and SS coils.
Beast tanks as in smoks line aka tfv8/12? Ye forget it, these coils last around 1-3 days depending on usage. With baby sitting these coils, and I mean really watching and maintaining them aka, use flavor less or extreme low sweetened juices, wash them out every day and let dry, vape way below recommendation, prime a special way etc. If not done tho, you'll be exchanging them every 6 hours lmao. Smok is the last garbage and not worth the frustration.
