The only thing that matters is that the 'tec' instructor is fully dived up and experienced at diving 'tec' dives, i.e. diving the dives all the time. They should have exemplary skills and use the correct kit.
Too often one overhears "tec instructors" promoting the tec courses whilst rarely if ever diving to tec levels and not in tec kit. This is the challenge of a shop where the vast majority of customers are doing entry-level recreational diving. They may have "thousands" of dives, but what's a dive?
Thus when choosing a technical instructor you should interview them about their diving experience. You want a breadth of experience and *lots* of technical experience, especially with twinsets, sidemount and CCR (few people dive deep on open circuit - it's way too expensive). Quiz them about how one should practice the new skills, especially the core skills at entry-level -- we all know it takes some time to perfect buoyancy, trim and finning. Doing a coaching day for basic skills (paid for) could be part of the 'interview' process.
My personal opinion is that you don't just go to your local dive shop and choose the technical course. You should firstly choose the technical instructor based upon their extensive technical diving experience. They're more likely to be well known in the diving community and be very active in technical training -- google is your friend. Most dive shops do not have instructors with extensive technical experience regardless of the courses they sell. That story of the inexperienced and poorly equipped 'instructor' above seems all to familiar.
