When I make a new account I'm usually an ironman or Hardcore ironman so going straight into player verses monster (PVM) situations isn't really a viable option for me as at some point I'll need farm skilling for supplies such as food so I typically start off as a skiller but that doesn't necessarily mean that that's what I'm classed as I enjoy all aspects of the game.
Although I don't have a preference between PVM and Skilling I know for a fine fact that Player versus Player (PVP) is not my favourite thing to do for the simple fact that if I'm an ironman and Hardcore ironman it's probably taken me x10 longer to get to same point most pkers will be at and then if they kill me I'll have to start again, which in my opinion is soul crushing. However I'm not one of those people that complain over being pked, I might be salty, but at the end of the day I've chosen to go into the wilderness to train as it's faster but with that comes risk of being pked.
As for group activities I think I'm going to be a solo player.
Hope that answered your question.
