"ImplosiaFX" can be fully self-descriptive if it will get some kind of the dynamics for performing something like real
implosion effects
Regard to the free version - it has only x64 support and other limitations in comparison to actual one, but the really unstable feature of free ifx - it's a custom data type called gigatopo ( v1.0 ), which can lead to unpredictable crashes sometime, especially when you trying to build your own trees with the implosia's nodes. And of course the actual version has "iterative" fragmentation that in my opinion produces most realistic chunks.
