My favorite system is Pathfinder, but I also have a love for 5e. I feel like playing online leaves something to be desired, even though that's my main means of play. I think taking the best of both worlds and combining them would produce the best results. The quality of life improvements that tech like Roll20, the d20pfsrd and DNDbeyond provide combined with the Interpersonal connection and ability to see people, roll physical dice, and smell the books would be the pinnacle TTRPG experience.
