The armchair/sofa dilemma

Now I'm in yr 11 I've had to start thinking about my future, most importantly what I'm going to sit on when have my own place. The choice is a sofa or an armchair but which one? I won't have enough/the need for both but they both have interesting pros and cons.

Pros-

Sofa-
1). Easier to lay on
2). More room
3). In the unlikely event I have someone over there will be enough room for both of us.
4). Comfy

Armchair-
1). Takes up less space
2). Probably cheaper
3). Can get a small table next to it on which I can place controllers, buns, pies and other essential items.
4). Comfy

Cons-

Sofa-
1). Takes up more space
2). Probably more expensive
3). Nowhere to put essential items other than the floor or a tray and I don't plan on getting a tray/putting my food on the floor.
4). Can lead to back/neck ache if possitioned badly as I may have to turn my head to see the tv/games console/PC hooked up to a huge wall mounted monitor.

Armchair-
1). Only room for one person
2). Can't lie down
3). Needs to be directly in front of the tv/games console/PC hooked up to a huge wall mounted monitor to avoid neck ache which may mean putting it in the centre of the room.
4). May be uncomfortable after long viewing/gaming sessions and there isn't much room for variation in position.

So there you have it. Four pros and cons for having an armchair or a sofa and I'm still no closer to making a decision. Therefore what I need is a sofa with armrests close enough on both sides for me to reach while still having room for freinds, fammily and a table for buns. Can you get those?
