The question is not which is better, but rather what your preferance is. The etrigger will allow you to adjust your rate of fir (ie. semi-auto, full auto, and 3 round burst). Where as the response trigger uses air to push the trigger forward after it has been pulled back. Therefore, in essence if you find the "sweet spot" you will have the trigger bounce of your finger and give you simulated full auto. The drawback is no control over the rate of fire. The advantage is that it has no electronics or batteries. So, again its your personal prefferance.
Tippmann A5 is way better
The Tippman X7 is better quality faster rate of fire and is just an all around better gun.
The tippmann 98 is more customizable, the spyder is smaller and easier to work on. so it depends on what you consider "better".
platinum is better because it has more content
Pokemon Platinum has more Pokemon so in my opinion Pokemon Platinum is better.
Nitro duck is a good brand, but tippmann is better in my opinion.
They are both around the same performance. The J&J may be slightly better, being ceramic.
a platinum card is better.
In my opinion, Pokemon Platinum is the better game.
Tippmann also makes the US Army Alpha series, so they are equal........ But the MR1 is not as widely respected at the Tippmanns are, most of that is due to the tough and durable nature of the Tippmann.
