On pt4 i'd sometimes have to wait for 10ish seconds for hands that had just occurred to feed through. You can click a refresh button when looking at your live hand feed and it feeds your most recent hands through almost immediately. This may be on PT4 I don't believe I checked for this. I liked being able to change the colour of stats and set up conditions which decide the colour of a stat to represent good/bad etc. I found the HUD stats were in the way of player chip counts or names etc often on PT4. The HUD can be configured easier and the HUD stats are in a fixed position which seems to work well with PS. Newer interface which would be easier for some people to use, but I didn't mind PT4 though it is dated. hand analyzer freezes but they are releasing hm3 soon and these issues are fairly minor. HM2 seems to have glitches every now and then where pop-up window e.g. PT4 is less laggy but has an out-dated interface. I have completed a 30-day trial of PT4 recently and have used HM2 for 1 day.
