MS (WPT & WSOP) vs. Atlantic City (WPT) events--which one?

Looking to take a trip to either of these locations next month. Would like to play in $1000 or less buy in, have a buddy that wants to satellite into the main event. I saw WPT event at Goldstrike has daily $540 buy ins, which is a big plus. Would like your opinions on:

1) which airport would be best to fly in for Atlantic City or MS (the 2 locations only 10 miles apart)?
2) better side games at either location?

I'm flying from midwest, never been to either locale.
