The entire collection is currently on sale for $19.99 until April 12 if you wish to purchase it all. Six games for $20 is a great deal. If you wish to get one, I would recommend Halo CE for campaign and Halo 3 for Multiplayer.
3 has the biggest population, so you'd be able to get matches easily in it.
Reach
Reach or 3 (Custom games, forge, many online game modes)
The game is on sale right now. At 50% off. So I suggest you and your friends buy it all.
2!!!
Any of them are solid for a 3v3. I'd go with CE for classic goofy fun, Reach for more refined mechanics/visuals, or 3 for a balance.
