best poker tracking software, is it worth paying for?

So I’ve been playing a bit more online poker since all the crypto stuff made moving money around easier. I’m not grinding the nosebleeds or anything, but I have noticed people talking up all these tracking programs, like stat trackers and HUDs and stuff. Seems like there are free ones out there, but most of the posts and vids keep pushing the paid versions. Not sure if it’s actually needed for low-stakes stuff or if it’s just overkill for a casual player with a tight-ish bankroll.

I’ve always been kinda old-school, writing down what I can after a session, but I do get how instant feedback might be useful. For folks using this stuff, do the stats really help you adjust as you go or is it more a case of information overload? I like getting an edge, especially if it means catching soft spots at the table, but I’m not about to blow half a buy-in just for some bells and whistles if I can avoid it.
