What do you mean they don't need to "check bank cash info"? I agree CEC is faster, especially because your work experience is Canadian work experience and is easier to validate than an overseas job. But you can be CEC and still need to show proof of funds, no? Either by current employment or bank letters of your current balance. I thought that it was during the PR process that CEC applicants didn't have to show proof of funds but they still had to do it for the OINP process.
In my case, I am an FSWP inland applicant. I have ongoing employment in Ontario (tech sector) but only 9 months so far, so i didn't qualify for CEC. Still, I used my current employment as proof of funds instead of bank cash info or bank letters.
