Hi KelvinKe,
well, the best answer to this question is probably that you should test it by yourself (21 days trial).
Let me try to answer your question anyways:
We believe that Flopzilla has no reasonable advantage over PokerRanger anymore. PokerRanger allows a specific evaluation of hand strengths on different boards like Flopzilla does. However, you also get this evaluation for two players (two ranges) with card removal effect, see the equities of all hand strengths, can manage your ranges comfortably and have a lot of other nice functions. For instance, you can see all you hands' equities against the other range illustrated in a matrix or you can get to know EV of singular actions. Also, you can import hands from HEM or PT4 to use these EV functions. Furthermore, it is possible to create groups which can be used to evaluate equities or hand strengths on specific boards... This list could go on for a while, so I'll just stop here.
There might be some particular functions of Flopzilla which PokerRanger does not provide; I simply cannot be entirely sure about that because I have not tested Flopzilla for a very long time. However, the number of functions that PokerRanger offers which Flopzilla does not exhibit is by far larger.
Equilab simply shows the equity and has some other functions which are not as clear as in Flopzilla. It offers a training function but PokerRanger has one, too, which has a lot of more functions. So, I would not say that Equilab is in any way comparable. Of course, for determining equity with more than 2 players, it is great. And it is free, so one cannot expect it to have a whole lot of innovative functions. As far as I know they do not continue developing this software, either, but I am not sure about this right now, so take this piece of information with caution. It is free, so you might just want to use it for equity calculations of more than 2 players (yes, PokerRanger does not support this), if you need it in specific calculations. Most users say that it would be nice but it is not that important, so we try to focus on other things.
Combonator's greatest function is the possibility to create groups and get specific output. PokerRanger offers groups as well and has a selector which is somewhat more advanced. Also, some people say that PokerRanger has a better UI and is clearer, but that might not be everyone's opinion. Of course, Combonator's output is great and we are working to get a better output for groups and other functions, as well. So, that might be something which Combonator is better with - at the very moment. On the other hand, PokerRanger's groups are combinable with all the other functions like the EV/FE tab.
Something PokerRanger does not offer is ICM calculation functionality, as this is tourney/SNG-specific and we did decide to put tourney/SNG-concerned functionality on a low priority. Of course, the software will still important those hand histories and the different tabs are very useful to improve your game as a tourney/SNG player.
tl;dr / All in all: There is a ton of differences between all of the tools. PokerRanger seeks to put the functions of all of them together in a way that it is most comfortable to use. A lot of our users said months ago that this was already the case. Now, however, PokerRanger has a whole lot more of functions.
So, you should test it yourself but we believe that you do not need a whole lot of tools, when you use our software, as it simply offers the same (and more) functions.
Of course, we are always very open to any kind of feedback. So, if someone strongly disagrees, feel very free to post your ideas.
Thank you a lot for your interest and if you have further questions, just ask!
Have a nice day and best regards,
Eisflamme
