This is a fairly vague question but:
There is no true "best brand" because there is no "perfect marker" that is a sever improvement over any other gun.
It would be safe to say that for "speedball guns" some of the best brands would be Planet Eclipse or Dye, depending on what marker valve type is "best"
For woodsball, most would agree, the best Milsim markers come from Tiberius and Rap4.
EDIT: For the Woodsballer that doesnt care about Milsim, we tend to like Automags, and Autocockers,
The best brand of paintballs are Marballizers.
Paintball grenades are a great outdoor sports option. The most highly regarded paintball grenade brand would be Empire. Another good brand is Tippmann.
No, spyder is an entry level company.
When someone is just doing paintball for the first time they need a paintball gun that is easy to use and light. The recommended one is a Tippman 98. Any of the variants will be good.
Dye is one.
No, they are separate.
Yes, all brand paintball guns use a tank or other source of pressure.
DLX, the makers of the LUXE.
