Baby sitting at 3 months what should I get

So our baby girl started sitting at 2 months and now that’s all she wants to do now at 3 months. She now needs minimal help before I’d have to assist her personally but now she’s good so long as she has a pillow or blanket. She is refusing to roll over and will get pissed if I lay her down. I am considering getting this

Or a bumbo seat what do you think?
