I've only played at TXPB and a field in Phoenix, AZ
I've only played paintball 3-4 times over the past 15yrs, 2-3 of those times at TXPB, so I consider myself a novice/beginner.
But, when my swim team wanted to go paintballing as a team-building activity, I knew the 45min-1hr drive up to TXPB would be worth it.
Only having actual experience with one other point of reference, I still must compliment TXPB on their fields. They have a solid variety of different fields-- speedball, hyperball, wooded fields, trenches, and a couple of attack/defend-the-base fields. Within a four hour session (with infrequent breaks), you may still not end up playing all of them.
They do a decent job of keeping up the fields (a few pods and parts strewn about a few fields), with little to no caved-in trenches or busted bunkers, and structures seem pretty solidly built.
Comparing pics to other area fields, I like the shade and cover that was present on most of the TXPB fields. There few that had limited shade were fine on a gorgeous Texas December day. :D I'll be headed back in a month or two, and will see how the warmer weather impacts my impression of the fields.
The few refs I've encountered there were young, but decent kids (not yet out of high school/college). They were eager to help, maintained a safe play environment, and answered any questions that we had.
Only once (several years ago) did we have a ref on a fairly slow business day that pulled what I thought was a pretty lame move. We had a decent sized group of beginners, all playing with rental guns. The ref apparently got bored with us, so he called his two buddies (that were apparently regulars at TXPB) to come out with their custom set-ups and tear us up. Understanding we didn't pay the extra fee for a private party that day, it still resulted in a quick way to turn a lot of guys off the sport, and really ended our day on a down note (whereas, we were having a good time prior to that).
Subsequent times, we paid for the private party fee to avoid this scenario, and it's definitely the way to go, though it seems a bit pricey ($75). The ref we had most recently, Josh, was a great kid that was back in town to work over the Christmas break. He was safe, reasonable about rules and managing our group, and did his best to accommodate our group of varied ages and skill levels and set up games that were well-balanced.
One additional note on private parties: the last two times I've gone there, I called about getting a private party (stating exactly that I wanted to reserve for a "private party"), and was told $35/player with no mention of the private party fee. This latest time, I specifically asked if the $75 fee was waived, and the person on the phone danced around the question without giving a firm yes/no. Both times, they sprung the charge on us when we got there. I didn't feel cheated, as it was advertised, but I did feel the person taking reservations should be more clear about it. (BTW, 25 or more players in your party does get the fee waived, from what I was told last time.)
Base rental equipment is BT-4 marker (used to be Tippman 98), mediocre masks, and a 4+1 pod/tank belt harness. You can upgrade to other markers, if you want. $30/person for 400 balls; $35/person for 500 balls.
My experience the last couple of times is that the first-timer guys go through 500 balls in very few games. First-timer girls and returning guys were able to stretch the 500 balls/person out to a good number of games.
They don't have much in the way of concession (just some candy bars, sodas, etc), but they do have a number of picnic tables in the staging area, and they allow you to bring in a cooler. They also have a grill, but I've never seen anybody use it.
Also, if the weather turns bad, they have a decent amount of space and seating in their building (that plays host to bathrooms, shop, concession, and proshop).
