Minceraft, as the name suggests, doesn't seem to stray from typical vanilla much, but, it leaves you with a very different experience. The modpack includes a much more detailed hud, more things to worry about, space, different player races, and other oddly specific stuff.
Looking through the mod list or just playing the pack should give you a feel.
Also, we made the mod pack while keeping performance in mind but also tried adding as much content as possible. I recommend going through configs in the "Mods" tab in-game to keep what you like!
Lastly, we have a teeny tiny support discord server ( https://discord.gg/xrutNUBa3g ) note: We aren't running an active MC server and aren't planning on for a while.
Please enjoy the modpack!
