I'd say Mac was a much better college QB, vs much tougher competition. In Mac's last year, they played an ALL SEC schedule, which is tougher than the usual schedule Alabama plays (therefore way tougher schedule than Love played his last year), there's usually some easy games thrown in against non SEC teams. But because of covid, it was an all SEC schedule. And what did Mac and the Tide do ? They went 13-0 and went on to win it all. Mac had an incredible year, and was spectacular in the NCAA Championship game, breaking the championship game record for yards (by 1 yard, set by Joe Burrow the year prior) and tying the record with 5 TD passes.
I wish Mac had Tom Brady here for 2 years like Love had Rodgers. That being said, it's going to be interesting to see how both do in their careers. Love certainly has some excellent young talent around him, drafted the last 2 years, and should be around him for some time. Mac has 2 TEs who are talented, but will be free agents next year (one of the reasons I was screaming for them to draft a TE in such a DEEP TE draft in 2023). Bourne will be a free agent as well. Only Parker, Thornton, Douglas and Boutte have contracts for next year.
