Ultimately, I'm not sure it matters, as long as it is good. I tend to like a more personalized version and yes, those of us with experience, can generally tell when it is and when it is not. One thing to think about is the job/career you are pursuing, if it is in anyway creative, personalize your resume, use your creativity...a designer for example, is not interested in a cookie cutter resume. Last thing, you may want to have two versions of your resume, one for "the machines" - many companies use AI to process resumes, so whether yours is personalized or not will make little difference, but AI tends to like standard formats. If you are sharing a resume with someone personally (online or in-person) you should personalize it to help differentiate yourself from the masses.
