-Loonion is a much higher trophy range farming strategy, used to keep cups up as well as resources. It is terrible if you are in crystal 3 or lower.
-I use a combination of barch and BAM. I have 10 minions sitting in my army camps to take up camp space and only use my barbs/ archers to attack. If i need the backup, I use the minions.
-You also have to consider the fact that when using minions, you have to worry about the air defence. If you use barch, you do not. Also, air bombs destroy BAM, so it takes more practise in comparison to barch. I think you need to consider the threats to both compositions as well as train time, cost, etc.
-I prefer barch because it is much easier to use and has a lot of room for error. BAM introduces minions, which themselves introduce a whole new series of potentially lethal threats such as the AD and air bombs, which kill the BAM comp. Giant bombs destroy both barch and BAM, so watch out for those!
