In my opinion, Mega Evolutions were the best.... In the anime, we got to see cool and fun battles which were totally awesome... The Mega Evolutions Special also showcased some of the powerful Mega-Evolved Pokemon.. Z-Moves were more prominent unlike mega evolution which resided with powerful and strong trainers... The Sun and Moon Anime has showed that by giving every companion of Ash a Z-Ring as well as a Z-Crystal.... This is just not good... Everyone except Ash, Kiawe are noobies with single Pokemon... Also, This Dynamax thing..Meh! Again, this will be prominent and will take out the uniqueness of Ash having special powers/moves...
