I do not know why you have to choose when you could have both. PF: WoTR comes next month so we could play it until bg3 finally comes, they do not even overlap. Honestly, I´ll be happy to have several games to choose from, some time ago finding a CRPG game in between a tide of MMORPGS or shooters was a titan´s quest.
Anyway, the new trailer of WoTR looks good
That said, it seems there are some strong feelings about that, judging by the comments and images you can find online.
