I like Braid, and use Spiderwire Stealth, but tried 20# Fireline at the end of the season, and I really like it. I get better casts. Farther, and smoother.
Braid is way stronger than mono, and much more durable. For instance, in off-balance/ackward rod positions, you can get better, more positive hook-sets with a braid, or Fireline. Since switching from mono, I have had zero breakoffs with Spiderwire Stealth braid, or Fireline. But, with a braid, it is still a good idea to check the braid if you fish heavy cover/structure, especially if you dont use a leader. I believe knots to be stronger with braids as well.
I think with Fireline you get the strength and "no stretch" like a braid, but you get the smooth casting of a good mono.
I will probably only use the 30# Spiderwire on my boat rod (9' Ugly w/ Okuma Baitrunner reel).
My 6' freshwater, 7' marsh/river/all purpose, and my giant surf caster (which I have yet to purchase), will all have Fireline on the reels.
If you want the best of both worlds, I suggest you check out Fireline
P.S. I, 99% of the time, use an 18" leader. Either an Eagle Claw black in 45 lb. test, or homemade 18" Flouro-Carbon leaders in 30# test.
