I've not used the predator v2 reflex, though it likely has a larger field of view.
The TRS-25, while decent, is barely ~1 inch diameter field of view. If you put the red dot further up the rail up near the barrel, would be faster. More like a scout scope. That gives you a better periphral view of what's around you.
I've used the bushnell on multiple firearms and it's a decent little optic. For a couple bucks more though, the sig romeo red dot (can often be found under $125), is a better sight though. I know it costs a little more, but the battery life is better. And where it has "shake awake" circuitry, you never have to worry about forgetting to turn the scope on in a hurry when you really need it because it activates upon movement. When it's sitting idle, it turns itself off after about a minute of sitting dormant. Thus conserving battery. And the very slightest least movement will turn it on.
There is an older version that bushnell used to make called the bushnell trophy red dot. It had your choice of 4 reticles. My favorite shotgun reticle is the circle dot. It works well for shotgun patterns, I think.
You can often find used ones for under $60. I have several and wish that bushnell hadn't stopped making them. It's a little bigger and heavier than the trs models. But I really like the circle dot reticle better. My eye just doesn't pick up on a tiny dot very fast. Getting old sucks.
Here's how the old bushnell trophy looks, though this one isn't mounted on a shotgun. I have others that are. This is just the first picture I could find of one to show as an example. Pay attention to the description though. Make sure it has the circle dot, or donut reticle as some call it. Some models of this were only made with the small dot.
