What didn't you like about it?
Have a look at the link I posted.
Inflator hose is pulled straight off a standard rec bcd e.g t-zone or similar. The outer shell looked flimsy. Bear in mind that when I was looking at it ; at a dive shop I was working, it was set-up between a new DiveRite wing and a new Halycon (recently purchased, as opposed to new design, I mean). It really looked like a cheap knock off a la IST or Divemaster Wings rather than the real deal.
The Tek wing is Bungeed where as the WTX isn't. Personally I'm not fussed either way, but the OP may want to take that into consideration when buying.

I'd be interested to hear about the new scubapro wing. Apeks is good, solidly made stuff, although I've believed that it wasn't as innovative and minimalistic as the likes of Halcyon, Oxycheq, Frog or DSS.
As regards innovation, I really couldn't say. But when it comes to minimalism, you're spot on. Side by side the WTX3 compared to a Halcyon Infinity is a big bugger, they have similar lift capacities as well. Although I've never felt that there was increased drag (then again my previous wing was off a Zeagle Escape, not a Halcyon)
The Evolve and the WTX6. Well I prefer a horseshoe shape compared to the doughnut as I like to bungee my SMB on the bottom of my BP, personally I wouldn't want my cell pushing against that area, as a doughnut may. It's an issue I accept with WTX3 but I like to leave the bottom of my twins uncluttered in case I want to add something to the tanks e.g D-rings. I find that WTX6 sits nicely on a set of twin 11's with minimal taco-ing, virtually zero with a set of Twins 15's.
I think where APEKs excel is in their pricing. Halcyon/Agir Brokk while nice equipment is incredibly expensive compared to the alternatives and I really can't see that their equipment justifies such a huge price hike.
