I'm glad your gun runs good, I did not say the CK was a bad gun and I didn't mean to hurt your feelings, I gave my opinion from my experience that the DVC run flatter for two experienced shooters that shot the guns side by side.
I responded to the OP question about why I would choose one over the other, the same as you have done. If I deal with someone that blames everything except for their quality of work, then I'm going to call them out on it and maybe that will help other people decide if they would like doing business with them.
When I said that I love my DVC (both of them), that was me mentioning their successes, they are great running guns. STI gets beat up on here pretty bad sometimes but I won't take offence by someone sharing their opinion of their experiences.
Thanks for sharing your opinion of your gun, I'm sure the OP will take that in consideration when choosing which gun to go with.
