There is a lot of good recommendations here so I am going to go back to old school gear...and I-go W-4 with it's airflow holes drilled out a bit is great for flavor with it's tiny little 20 mm deck. I like the Magma as well, the Storm V2 if you can build vertical coils is a good one and it's got pretty good airflow...it's like building a dual coil Geni without the tank
If you want clouds too (and I know I'll catch shit for saying this....) The Mutation X V3 for what it is has much better flavor than I thought it would. I have an old Patriot V1.2 I got an Affinity Pyrex Glass cap that has 1/8 in airflow holes in it that gave that atty new life and flavor. I also have a Manta V2, it's not really good for super low sub ohm builds, but above point four it's got even better flavor than the magma. Even an I-go L, again with the airhole drilled out, I still think is a great little atty with a 1 ohm coil for testing out flavors and still use mine for just that and it's cheap as dirt
