slayer is fine, don't listen to people who say it's bad. still strong in smallscale (SC, city, 6v6, etc) and perfectly fine in wb if played properly. it is weaker than before in wbs and open but is more than playable and still brings powerful utility like shatter limbs and IHD.
BW is definitely stronger for average gameplay now though with less skill required to perform your job at an acceptable level.
play whichever is more appealing to you and don't worry about meta slaves/incorrect opinions of players that don't know how to play.
