Again, I'm not saying BT is outright better, nor am I trying to compare PG to SR. I've just had a fair number of games in which I wished I could've built a BT instead of an SB, games in which I'm not dying much and I'd like to have the AD constantly there instead of having to aa to build it up. Seven autoattacks is a long time, even at 2.5.
But SB is just better for the game mode. You shouldn't be going too long without auto-attacking something in aram, whether it is hitting creeps or poking at opponents. It isn't going to be at zero stacks for very long if they do drop off.
I also think you overestimate the number of creeps you would get to stack the BT. You will not get stacks quickly. Many mages have far better aoe creep clearing ability. An AD would be lucky to get three cs per wave. You're probably going to fight before five creep waves have come.
Like I said before, BT on aram would be a bit of a trap. I think SB is generally under-appreciated for what it does, so a lot of players would instinctively go to the BT since it is often considered "better", but they would really be doing themselves a disservice by buying BT over SB.
