What do you mean "more complete management?" If you dont know the capabilites of each, you should learn them. They are all capable units of controlling an engine more powerful then you can imagine.
I'd say in your case, a reflash is your best option.

Since you already have a boost contoller, you could just get some sort of minimal feature AFC. That'd be the cheaper way to go. If you are going to spend more, you might as well get the reflash. If you plan on making bigger or repeated changes, go with a utec. Its not a matter of "complete", its a matter of where you wanna go and how much parameter granuality and repeated modifications you need for tuning the ECU.

Jason my goal is to eventually upgrade turbo, intercooler (front or upgraded top?) with this in mind based on my research the utec may be more flex b/c with every upgrade I'd have to reflash...What modifications should be done prior to going to the utec? I'm leaning towards some suspension to offset my power upgrades (JIC coils or tein for my wagon)...Apprec it, ty

Simplest is a reflashed stock ECU. A more spophisticated option is the Xede piggyback, which has complete control over boost, fuel, and timing, and is the next least expensive option. The utec operates similarly but is more expensive.

Okay to clear this up based on my original goals: "my goal is to eventually upgrade turbo, intercooler (front or upgraded top?) with this in mind based on my research the utec may be more flex b/c with every upgrade I'd have to reflash...What modifications should be done prior to going to the utec? I'm leaning towards some suspension to offset my power upgrades (JIC coils or tein for my wagon)"
Would my most flexible option be the utec because I can download after upgrades and would not have to send in to reflash?

I would say the UTEC is a good idea but there's not going to be a UTEC for the STI for 4-6 months. If you're driving a normal WRX then you're golden. But research the Vishnu XEDE as well because all their maps are shareware also and you can also download their maps off of the internet depending on what mods you've completed.
