I think you should do both, I'd recommend AOW first and then some diving outside of a dive cert class before you go for intro-to-tech (ITT) type class.
As mentioned above already, at the very least, AOW will let you get on trips locally and, more importantly, when you're on dive vacations. AOW gets bashed a lot (and sometimes rightfully so) but it's extremely convenient to have and, for me, was worth what I paid for it.
Your profile doesn't say how many dives you have but from a different thread you had, it looked like <10. ITT will be extremely difficult and frustrating at this time and I doubt you'll get much benefit from it. It's a hard class as it is and you really need to be comfortable in the water with SCUBA gear before you pursue it. Having said that, definitely do it after you've gained a little experience - it's one of the best courses you can take regardless of whether you ever intend to pursue technical or any other advanced type of diving.
