Not always and it is not so simple, it depends on various things (light, distance, dof) but I agree with him that Pentax AF can't be trusted by default.
If you don't have a good light, chimping and reshooting in MF is usually necessary for closeup portraits with shallow dof.
I still have K-5, also I have K-1 for almost a year and Sony for 2 years.
Sony EYE AF works almost perfectly, and it is better option for portraits than Pentax.
Sony is also better for action in general with AF-C (lock-on flexibile spot works very good).
Sony also have slightly better wifi remote control software but mostly because Image Sync can't rotate view to landscape mode.
For everything else K-1 is a better choice.
At least for me.
