I really don't have preferences. My PC and switch are located pretty convenient, so I just play whatever I feel like. Plus, some games on the mobile. But if I would choose what is more comfortable, I would say Switch because I could carry it around
Actually, you can use a projector to cast the image onto the ceiling, so that way you can fulfill your wish of playing games on a big screen while lying in bed~ So I don't really care whether it's on PC or a portable device.
I like playing on my bed with pillows so I definitely prefer portable devices like the switch or Vita. However, if the game is unlocalized I mostly play on the pc since I depend on Luna translator. I guess the benefits for the pc is that the bigger screen allows me to admire the art more. CGs on a big screen are just a different experience
