General 3P Combiners Questions

Greetings All,
I've never purchased any 3P product, but I admit many of them look amazing. I have a real desire to complete my combiner collection, especially since with the "Siege" reveals there looks to be nothing in that regards for 2019 (I know they could come back later but...)
As of now we don't have a modern Hasbro Piranacon, Monstructor (or Dinoking). We also don't have modern updates of:
Raiden, Landcross, and Road Caesar.
The first 3 I know 3P companies have developed. I just wonder if they are worth purchasing, or should I wait another year for Hasbro to reveal their 2020 Generations line?...Also I don't believe any 3P has done any rendition of the 2nd trio I listed (though If I am wrong , please let me know).
Additionally, I know there was one 3P company that released a version of Motormaster that was compatible with the Hasbro/TT developed combiner system for CW/PotP. Is anyone aware of any other 3P product (Voyager or Deluxe scaling) that is also compatible with this system? Any assistance is appreciated. Thank you so much.
