Not really an expert but I've heard some stuff
Personally I don't use a HUD and never have but my husband has tried several. He seems to like Poker Tracker 4 the best out of the ones he tried.
Also, it seems a lot of the streams use Poker Tracker 4 also or at least most of the ones I watch.
I have often thought about trying one to see if maybe it improves my game because I have heard mixed reviews...some say it can mess with your style of play and others live by them. However, if I were to try one it would be Poker Tracker 4 simply because of all the positive feedback I have heard. It seems to have a lot of different features.
