MilSim is short of "Military" and "Simulate/Simulation". It covers everythings related to Military/Police from Gears to Activities. Such as Survival BB-Games or Scenario Paintball Games.

It depends on whether you want to p play good or look good.

If you just want to have a great looking marker, go for a BT7, BT15 or any of the T68's with kits. A Tippmann with a body shroud also looks nice. If you want some extra realism, go for a MILSIG or T68 with magazine feed.

If you want a good playing marker that's still milsim, you can get a SP1 or a Ion with Milsim body kit.

Nearly any spyder model will shoot the same as as the Bt omega. However it has a less durable design and will not look as "milsim" as the Omega was built for.

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,

All paintball guns have the same "power" since they are regulated at fields. As for "looks" there are milsim markers like the x7 or speedball markers like G4.
