You can be as neutral and factual about it as you want, but Giggs was here for United. Ronaldo saw United as a tool to get his goals, which also was why he got to where he (and his mom’s dreams) aimed (Real). But in the end this is a United forum, where we judge what United players did for the club and that is the comparisons here - no doubt Ronaldo’s career was overall the better, but let’s also face it - Ronaldo was and is all about himself. How do you adore someone who’s not about everyone else than himself? That’s also a great deal about the legacy of what you leave United with.
How do you compare the two? Longevity and an eye for the team vs a one-man-team? What are the metrics? On pure stats, sure you can say Ronaldo was just better.
Edit: Also, id say your post is BS. At age 35 or close to (34?) Giggs tore it up. The 7-1 Roma game, man that was maybe even the peak of him. I’ll say you’re completely wrong about that age with Giggs. He aged like fine wine between 30-36. Everytime he took a throw in or got close to the fans, everyone just appreciated him, cheered him - unlike a Rooney who we all just wanted rid of in the end. With Giggs it was different. It was class. Many seasons in a row.
