You are comparing many Canons with the lowest-end Olympus. That is kind of unfair to the OMD series and the quality of the Zuiko PRO lenses.No, I'm a Canon person. AE-1, T70, AT1 (given), A1 (inherited), D40, A570IS (first 'good' underwater camera), 7D (current underwater DLSR camera), G16 (once again scooter camera).
I just like the way the Canon works.
(kinda like my wife has owned several Pfaff sewing machines and loves thew while her sister is a Bernina lover)
I think it all depends on which system you got into first. Eventually you have enough of the accessories that it's really too expensive to switch.
If you want to say you are a Canon person, not a TG6 person, OK. But it is kind of a broad brush to just say Olympus.
