I've been playing only Mineplex Skywars for months now and I have just started playing only Cubecraft Skywars for about two weeks. (Mobile Player Here) I can tell ya'll that Skywars is way more fun in here, just because there is more PvP and less confusing and annoying powerups like Mineplex. In Mineplex, it is based a LOT on pure luck, because of the ores that give you stuff and it feels more confusing with all the spells, "Boom boxes", and all of that magical nonsense. I like it here, it is not based on luck, everyone gets different gear but with ups and downs that feels fair, and it is based on skill and awareness.
But it isn't all flowers and sunshine... In months of playing Mineplex, I have only seen 2 HACKERS. Here, I have reported like 10 HACKERS already, and there are still more that I couldn't report... and I've only played here for ONLY 2 WEEKS.
That is my opinion, let me know what yall think. : )
