I have all three, an HCCT, a strobo, and an ECCT. The HCCT works well, but is cumbersome to move about, it is mainly for show. I used a strobo for years, but know it is in the shop and used to just test certain things. Once, the dirty work is done, I bring them in the house and use the ECCT. The ECCT is more particular, so more time is needed to set them up, but once properly adjusted, our cars run much better. The ECCT is also portable and much more reasonable than a HCCT.
