Ah, this debate still rolls on.
Well, I don't feel either one is tougher than the other, nor do I feel they are easier then the other.
Several points of both have been mentioned. Hiding, creeping, stealth,firepower,all of these are part of both games. I have hid in a snake,noone saw me until they dove in beside me. That is funny to see looks in thier eyes. Point: you can hide in speedball as well.
Firepower, yes,electros and other high end guns can push some BPS's, but I have played in scenario tourneys where only blow-back mechanical have been allowed, full auto from A-5's where allowed. There where even a couple of SMG-68's playing. Granted, they don't shoot as fast as a timmy or DM, but thats still a whole lot of paint looking to get midevil on you.
The single most important thing that I was taught is this:
If you have played for 30 years, you still don't know all there is to know about paintball, and if you have played for 3 years or less, and have the fastest gun on the market, you don't have all the answers either.
Point is, we can all learn from each other.
Sure, game on in speedball means instant firefight, it's time to start shooting, get to your bunkers, get your angles,communication is key.
Remember this,in both games you have new players or rookies. In speedball,they don't move or shoot as fast,same in the trees.Most seem to opt for trees,therfore the game tends to slow a little. I know a group of 5 guys that could take on 30 of us in the trees,and win without loosing a player from thier team.
Game on in woods means we got some moving to do first,go with the command plan,and even then, expecially in scenario, could mean "do we have to or want to engage this group,could it mean us winning or loosing the mission or game?" Communication is key. See a point here?
And don't confine yourself to one style of your favorite play.Play in the trees with your DM-5,Angel,Timmy,etc... just be nice to the rookies.
Play a speedball game with a pump.
We used to do drills with limited paint, or start with empty hoppers.
Heck, do a pump only day sometime. For some of us old dogs, we have some great memories of those days, because thats all we had.
In conclusion, I feel they have the same streghths/weaknesses for gameplay.
