Not much to talk about when Kaguya is clearly much better in all aspects. https://twitter.com/vicmitro/status/1254158212133269505

Maybe you could argue Toradora is better for focusing on romance more but I don't think it does a better job when Kaguya actually gets serious.

Also it's kind of crazy how Kaguya has one of the most likable casts and Toradora has one of the least likable casts.
