I disagree.
1) I’ve never seen PBA post long excerpts from seforim
2) PAA doesn’t use the r word in every other sentence
3) PBA uses a lot more abbreviations than PAA (example: DY vs. PAA spelling out DaasYochid)
4) PAA isn’t rude
5) PBA is sharp witted, while PAA has more of an intellectual sense of humor
Whoever posited that they have similar styles has no idea what they’re talking about.
