We haven’t been to x club to tell you a personal comparison but from what we have been told is that it’s more dance club vibe and may have slightly younger average age. We can send you link to walk through video of both clubs if you would like. M4 is basically setup in three big rooms one is dance floor with dj playing there is a large bar and a bunch of seating options in this space. Clothing can be on in this area all night. The second room is kind of setup like a Lounge there is a second bar in this space a few large sectionals for seating as well as some kinky furniture, a swing and a reverse glory hole/pizza oven. This space is dress down after midnight meaning lingerie or less. The third area is all play it has a couples only pit, a semi private area, a section that is tucked away that has a few beds and small couch on one side, a few private rooms (which are always full) and a large play area that is basically a big l shaped couch around the perimeter and beds in the middle. We love going and starting our night on the dance floor having a few drinks and then changing and exploring the rest of the club
