IMO, what you buy/use will depend on where you intend to fish most of the time and how much you're willing to spend. I use different set-ups, from a 6 wt to a 10 wt, but I'm fishing primarily tidal creeks & rivers, with occasional trips out into the Chesapeake Bay. This is really brackish water & not that salty. When I'm targeting larger Stripers, which for me has been anything from 18" up to 30", I'll use a 9 or 10 wt most. This is because of wind & the size flies I like to throw. I've caught hundreds of Striper's over the years, but have yet to land one over 30" on a fly. But, I'm OK with that!
I agree with Rip Tide about the reel. For those species, it's not necessary to buy anything special. I use Okuma Integrity reels, which have worked well for me. On my 6 wt is one of the original Lamson LP2 reels (pre-Waterworks), that I also use for LM bass fishing in fresh & tidal rivers. I've landed 30" Striper's with it.
However, if I was spending more time in true saltwater, I would likely want a more corrosion resistant reel and agree the Lamson's would be a good choice.
I've become very fond of TFO rods, but also have a couple of Redington's. TFO are very good rods IMO particularly for the price.
I have fished on the SC coast with what I have, but not extensively. So, what I use for the brackish water has been fine for the occasional trips to "real" saltwater too.
