From what I have seen in competition NSB 90 and odyssey/stinger 2150 still get used more and is preferred in 1-2 battery street classes in DB Drag...that is after tests against Batcap and PM ,not sure about the 3000 but a bunch of people were going to use them at finals and from results I didn't see any of the top guys use Batcap or Powermaster. In street A (smaller battery 650 cubic inches) odyssey 1750 is the king of the hill with the NSB 650 cubic inch battery being in the mix.
Also if you are wanting to use what people use in street class competition you should also know that the way they load down their amps and the limit on the batteries that it is not a very good way to run a system daily. Its very hard on a battery especially if you play the system for more than a few seconds without rewiring and/or taking amplifiers out.
In Street max people use multi cell batteries that can more than double the cost of what you can get a 3800 for. They are batteries like the CS9000, Matrix battery and the Batcap 8400. Out of those the only one I know that anyone has talked about using it daily is the CS9000. The batcap 8400 goes for $1000+
Biggest factor in your system is going to be your build. If you do a good build you will be upper tier regardless of which battery/batteries you will use. There is a lot more to a good battery than what it can do for 4 seconds, especially if you plan on using it for daily. Go to small or too few batteries for your situation, even though they do great for 4 seconds, you can deplete the lead in the plates of the battery causing it to fail over time.
