I find fun in both.
Parties = total decimation of anyone but sometimes hard to get a lot of kills since everyone (I am assuming for everyone else) has good teammates so they take a lot of kills ending the game quickly.
Going in alone = you are the team, (at least for me) all of your other 4-5 teammates don't do crap meaning you rack up the kills in slayer games and run the show solo.
This effect is the worst in Doubles.
Everyone except you will be braindead.
