Couldn't have said it better myself if I tried. The one thing I do like about flows (and that's limited) is that it is the "traditional" muscle car sound. Which is why I crossed them off my list first. I would def get that with a new midpipe to really change the sound. A nice catted X should do the trick, O/r x if you don't care about emission standards and inspections. Youtube will have all the vids you need to make your decision.

I'm about to get a new exhaust system, and I was heavily considering a flowmaster system for a while. I started researching the Magnaflow Magnapack system and really began liking it. It looks like it will give me the sound I want with less drone. I think the a Flowmaster exhaust system and a Magnaflow exhaust system are very similar in price. So listen to some youtube videos and figure out which one you want.

Well my flowmaster mufflers have baffles loose in both of them and I just put an O/R x pipe on with them and now the baffles vibrate like CRAZY!!! I need new mufflers. I hate magnaflow exhausts. They sound too much like a muffled fart. The tone is not good in my opinion. I dont know what mufflers im gonna put back in because there are just too many to choose from and i dont wanna do this again anytime soon. Probably just put flowmasters back in...or maybe MAC flowpaths with the o/r x will sound good. Who knows.

You need to ride in my car then. With the right setup chambered mufflers can be down right obnoxious..../beautiful 
@OP: Skip Flows and go with MACs. I wish I had in the beginning. If you want super 44's go with an o/r x, they sound pretty nice in that setup. But if you plan on going with 40's, just get a pair of MACs instead. Been down the flowmaster road with 40's and 50's, and they just don't sound quite as good. I will say 40's DO sound good with an o/r h, just not as good as flowpaths

But when you go with an O/R Midpipe you are most likely going to throw your Check Engine Light for the O2 Sensors telling the computer there are no Cats. You will want buy Mill Eliminators to trick the Computer into thinking that cats are there. or you can go by a tuner and just turn the o2 Sensors off. Americanmuscle.com was selling the Mills for 17.00 a little while ago. not sure if they still are.
When you install the MILLS make sure your battery is disconnected. Since you have an 04 GT you will need the 02 Sensor Extensions i believe.
