Which are the three? I just want to find one that you don't have to trim, can have a winch, put lights on, and have recovery points.
Read his directions.... your trimming a small amount of metal. It's so easy a drunken monkey could do it and no one would ever know even if you did go back to stock. IMO some "other" bumpers require the same metal to be removed - they just don't tell you about it and it looks like poop and rubs when you install it.
There may be more that I don't know about.
Either way look at designs yourself instead of relying on others opinions. This is a large purchase and you should be well aware of what your buying.
