I only vape MTL so i have more than 2 favourites.
1. Flash e-vapor Fev 4.5+s (yftk clon)
Amazing MTL with air screw alternatives. I use 0.8mm which provides a really tight draw. It is incredible for ADV with tobacco liquids. The steam is nearly cold. Very simple build, solid as rock. The dimensions of this tank is big as you can imagine however you know what they say, "small is good but big is BIG"
2. Svoemesto Kayfun v4
Considered as the best MTL atomizer ever. Hard to build, so many pieces around appx 50. The flavour and the smooth vaping experience with throat hit, incredible. Cold-warm steam.
3. VWM Mods Integra
My favourite ADV tank for fruity liquids. Tight draw, incredible flavour. Easy setup with 13 different air options and top and bottom filling options. Handsome and solid. 6mg nic is the limit for enough throat hit. Cold-warm steam.
4. Svoemesto Kayfun Lite 2019
My other ADV tank besides Integra. Incredibly easy setup, so many customization options, both clone and original. Kayfun original accesories, steamtuners, klon etc. It is hard as rock, very tight draw with xs pin which is adjustable. I use the 24 mm version with extension kit, huge tank. Warm-hot steam.
I look up to some other tanks such as ESG Skyline (i am not a fan of pastry but this tank rocks with pastry). Gus Menelaus 3p tight deck (good with tobacco and very good looking tank however very hard to build).
