I'll say BT.
I really found them distasteful for putting that high of nicotine in their pods. At first I gave it/them a pass because I didn't understand what salt nic was. I first saw the disparity between 3/6/12/24mg-freebase vs 50mg-salt and thought there must be some sort of 'translational' thing going on. Then I learned that 50mg-salt was in fact the same amount of active nicotine as 50mg-fb. I then also learned that salt nic was a more addicting type than FB (but has its uses).
... And then my distaste for them was born.
Although I will say the distaste isn't so much for what it actually is.. It's more for introducing such a device/nic-strength/nic-type combo at a time when vaping was already under attack by The Ignorant And The Malevolent™.
If it came out later on, when people hopefully become enlightened enough not to immediately bring out their pitchforks the moment they buy into emotionally-charged BS propaganda all the time (for just about EVERYthing) - then it might not be so bad. Right now though, we have too many ignoramuses leading too many
blind ignoramuses.
