One should try both games. It is personal preference in the end.
I was not that far in WotR but I never faced noticable bugs, so I cannot complain.
Where WotR is clearly better than BG 3 for me are parts of immersion. I don't like being able to send items to the camp from anywhere in BG 3, for example. I'm not a DnD guy and don't know wether the postal service of Faerun is generally that good, but I doubt it. My biggest gripe with BG 3 is the "carry situation". If I have a group of travelling heroes and heroines, I want to see some travelling stuff, for example to store the neccescary toilet paper and other camp items. From the free floating weapons without sheaths to the missing backpacks, here is BG3 so much worse than WotR, unbelievable. Shields in BG 3 seem to be foldable and be put in the pants pocket. It's sad.
For most of the rest however, I prefer BG 3. I like the graphics and the style better than the cartoonish WotR. The stories and the participants in both games are seemingly RPG game standard, so superficial and bland. I don't expect more. If you want a good story with believable characters, read a history book. The story of BG 3 is a bit more mysterious, ok, and, important, I like the companions in BG 3 much more than the overdone specimen of WotR. Voice acting is an asset in BG 3 and a kind of burden and hindrance in WotR. Combat in WotR for my taste is boring or annoying, or boring and annoying. Combat in BG 3 can and should be improved, but I like it much more already in the current state.
As conclusion, I prefer to play BG 3 EA further than to progress in WotR.
