Right now I have a Revo STX, Shimano Citica D and E, PQ, Daiwa Zillion. 

I am thinking about picking up another reel for my birthday but I am having troubles with which one to get.  I am stuck between Curado e5, Revo SX, or another STX.

I mainly throw soft plastics and jigs but work in cranks/lipless and spinners also.  I use my Citica for my cranks/lipless and spinners because of the slower gear ratio, and was just thinking about leaving that as my main crank/spinner reel and just buying another higher gear ratio reel like a SX or STX.

What do you guys think, would it really make a big different to switch to a 5.x gear ratio for cranks/lipless/spinner or should I leave my Citica as my cranking reel and buy a SX or STX?

Unless you consistently throw a DD22 a 6.3:1 ratio reel will do everything you want to do. A Citica D or E is also a 6:1 ratio. You can but gears for your Citca D to make it a 5:1 ratio if you really feel you need one. Most will throw a DD22 very little, dependent upon the lake you are on. If you use mainly plastics and jigs you would want a higher speed reel to take up slack line, a 7:1 may help, but a 6:1 will do the job. The main thing is to buy what you feel comfortable with and would use. Believe me I have my fair share of rods, reels and lures which I bought because I wanted them, not becuase I use them. Best laid plans will prevail.

Very true, I forgot about swapping gears but I hardly ever ever ever throw a DD22... 

Okay a SX or STX  ;D  I love my STX but I have never fished the SX so I dont know if I would like one or not lol.  I have heard really good things about the 2010-present SX's
