Braid is horrendous in the rocks, but it excels in water hyacinth and lily pads.

It saws through them like butter.

Four or five foot leader of fluoro, tied with an Albright Special to the braid works great on my spinning rods.

I can reel the leader onto the rod, and cast without a tick as the knot passes through the guides.  It will tick when reeled in because of the nature of the knot.  On the way out, the braid leads.  The tag end offers zero or nearly no resistance.

I like the braid for its thin diameter, and its lack of memory.  Casts much better than the equivalent pound test of mono or fluoro.  

On baitcasters, it's probably not as noticable.

The great thing about fishing is that we can all do it our way.  Whatever floats your boat is the way to go.

Power pro may or may not be the best but in my opinion it is not outdated.  It works fine with a minimum of issues and it's very strong.  I catch fish that are much bigger and stronger than any bass on 10 or 15#. When I'm bass fishing 10# PP handles lily pads, weeds and stumps with no  problem, at least not for me.

The debate of one line against another or braid vs mono is getting old, it boils down to personal preference, not scientific fact.
