Skirmish - Cannot compare, it's sort of like comparing a Viking and and Impulse, no contest. However, Skirmish is a bit more expensive, and it's so crowded you usually can't just go play a game at a field you want to.
Dailey's Paintball - Only played on their speedball field. Very good, comparable to Command Post, they have since gone out of business though.
Command Post was the first paintball store field I played at. My first expirience was terrible, but it was not bad because of command post, my BE raptor wasn't working correctly. I joined a team there, the Rogue Warriors. We played many games there and had alot of fun. We regularly goto the Picket's Charge game, so look for some crazy boys in grey. The Pickett's Charge game is very fun, single shot (without hoppers) during the morning, after lunch it's regular rec ball. The game is certainly worth your time, goto the store to find out when it is, usually in late August. I have not been there recently, however it did not seem to cater to speedballers very much. The new sup air field was nice, but I heard they have not put it up for the most recent games. I haven't seen the hyperball field.
If you plan to go, and you live further away...The Inn at which CP is located at has a deal, 40 bucks for 2 beds per night if you play at CP the next day. Us Rogues took advantage of such a deal. Alot better instead of driving up the morning of a game of play.
I gave it an 8 because they could expand more. If you don't like playing in the woods, don't go there.
