If you're aiming to create a community server where everyone can get along and stuff, I suggest creative, survival or factions. I voted for mini-games though since I feel that if a server has more variety, it would attract a different assortments of people. Although, mini-games aren't that fun by yourself, so you'll need to build a community base first.
If you become successful, I'm sure the PMC skinners, such as me will use your server to hold meet-ups in instead of Mineplex, Hypixel or HiveMC and such.
If you want, I'll see if I can help with the advertisements since I'm really interested to see how this goes ^.^
