It all depends on the reel IMO. For spinning PP will cast further and it has improved over the years. I have not lost that many fish on rocks with it but I have broken off a few over the years. None recently though. 2 years ago I loaded spool(s) with most of the popular brands and did a head to head cast and crude fiction test. PP outcast them all but was not as rugged as some of the others. I was going to write a article about the results and see if the fishermen would publish it but I thought the "tests" were not scientific enough and would be the subject of a lot of critics soi I said the hell with it.
But IMO if you fish heavy rocks where your line is rubbing on rocks all the time I would go mono. It has better abrasion performance then any braid. Test it yourself...get a 3-4' lenght of line and put tension on it and scrape in on a rock. Count how many passes you go before it breaks. Do the same with mono. Come to your own conclusions. Most tackle shops will give you 3' of line for noithing and you can test it in their parking lot. For my money braid will catch you more fish though. I have stood next to guys fishing mono who could not work a shad along the bottom for very long in a strong current while the braid could and I pounded fish while they had a very slow night. Several guys asked me "what the hell is your secret?"....braid line. I notice they fish with it now too.
You can fish currents better, deep better, distance better , hookset better, fight the fish better, no UV problems, lasts all season (maybe more)and I love the sound it makes as it screams thru the guides. The downside is abrasion resistance is worse and it cuts your finger like a razor (on spinning) so use tape or some protector. On conv you can use other brands with equal success but spinning I like PP. Fire line and spiderwire are stiffer lines and work better on some older reels not desigened for braid. Tuffstuff seems good for conv's and stren braid was pretty good on spinning too but I can 't recall the details. One tip: If you put PP on a old penn you are in for a nightmare. Penns are not designed for braid they lay the line on the spool wrong for braid. You want braid to lay like rope on a big spool, not back and forth back and forth. This way when you cast it comes off smoothly. The only braid line that works (IMO) in penns is fireline and that is too thick for my preference.
I am not an expert. I am just telling you my experience with this stuff.
You have to test it out for yourself everyone has their own preference...as ususal: " Your mileage will vary"
