BE112 is another version of 801 as well. Just recently got some of these and so far liking them. Haven't yet tried the 302 (which I believe - not sure - is Joye). But, on my GLV2 5V, I am finding I like 901 the best - so far. I think juices play a big part. Juices, at least for me, seem to respond differently on different attys.
For me, fruity and sweet juices (rare occasionals for me - shorter vape sessions too) seem to taste better at 3.7 on 510s. I am finding I like my tobaccos and menthols better on the higher voltage with various attys. At 6V, I tend to use 4.5 oHm attys and 3.3 ohms on 5V.
Even within the tobaccos and menthols, I find variations. For example, I like Tasty Vapors juices better on 901 and Vaperite juices better on 801. But, still many variables - probably a never ending experiment!
BTW, anyone who hasn't tried Vaperite juice(s) - is missing something IMHO
