I don't have any clue as to whether this is the best or not.
You can try out PreADMET. (https://preadmet.bmdrc.kr)
The best way would be to compare results from various softwares and check the rationale and principles behind how each of the prediction programs work. This would help you decide which would be a better fit for your research.
As the other already mentioned some of the software that I usually used during my research (e.g., SwissADME, Admetsar), I would also like to recommend pkCSM (http://biosig.unimelb.edu.au/pkcsm/) for your references. I hope it helps!
