Tigerstripe, been there done that. Too dark. Maybe you would get away with it in a murky swamp in Louisiana, otherwise it was designed for the tropics.
It was fine in Vietnam. It was replacing ODs, so, how could it go wrong.
Wouldn't touch it in NorthAmerica. It sticks out badly when the background colors are lighter than it is, which is most of the time. Tigerstripe, it was thought, did have some possibility that it helped hide movement, due to it's horizontal line approach.
There is active and passive. The World War 1 example that Coldwood used is a Passive Disruptive pattern. It disrupts the silhuoette, in an effort to break the edges, and is passive because it trying to make the object blend with it's background. Military camo is typically passive and most likely edge disruptive.
Multicam is strange. the places it works, it works very well. One place where we do NOT like it is, frankly, in the woods! It works better in an urban setting or grassy plain, meadow, desert, etc. Also, their website shows it in specific places with specific lighting. And the cost is just prohibitive. For me, the jury is still out on Multicam.
As for the various other patterns, such as Flecktarn, (Flectar) they use the older principals such as US Woodland and Tigerstripe. They work OK in the region they were designed for. I've tried Flectarn in the fall, when the leaves are changing.
With the exception of Multicam, I own a set of just about everything.
Woodland, Flacktarn, Austrian Dot, DPM, Tigers, 6-color deserts (Chocolate chip cookie).
What do I wear? MARPAT. All the way. It's not a gimmick, it works.
