I have A Halo Triton Kit as well as An MVPv2. Halo was where I started. First thing to do is replace the coils with the lowest Ohm you can get from the Halo Website. That will improve you vaping experience with the Triton tremendously. Made a big difference to me anyway. The advantage to the MVP is adaptability with Watts and Voltage to different juices and tanks. The thing I dont care for with the Halo is the threading. it is different than 90% of the tanks out there. Just their preference but most shops sell the ego threaded items and dont carry the 808 that halo uses. This means you have to order the parts for the Halo. Good Luck and Happy vaping.
You don't always want lowest ohm. I may be wrong as I'm fairly new but doesn't that make for a hotter vape? In which case certain flavors (Belgian cocoa, fruit flavors) wouldn't be good unless you have a vv and can dial it down
