I have both the tactical and the stryke shirt and pants. The main difference to me made me lean towards the strike. Stryke shirts and pants appear less baggy and lighter. Unless you like the baggy style, the stryke will make you look leaner. I use the strike for appearance purpose and the tactical for field works. The strike's collar, sleeve and overall looks better. I believe more time was spent on designing the stryke. Stryke does cost more but worth it for my purpose. Buy it when on sale.
I have only had the shirt a couple weeks. I really like the shirt, and so far it has held up well. It is well constructed so I believe it will last a long time. I would like to obtain a few more, but at this price point I will have to wait.
