Tyrod won a road game against the team that was (a) worst in the NFL last season, (b) was starting a rookie QB in his first game with no preseason, and (c) was without one of its best defensive players (Atkins). And that win required the opposing PK to miss an easy FG that would have put the game into OT.
Herbert lost a home game in OT against the defending champs, after learning he was going to start 10 minutes before kickoff.
If you truly cannot see which outing was more impressive, I can't help you.
Let me also point out that home vs. road doesn't mean nearly as much through these 2 games as it would in a normal season.
As for which QB gives Lynn what he wants, my reaction is that what Lynn wants isn't necessarily what is best for the team. We've seen that repeatedly during his tenure. So it doesn't carry much weight with me. YMMV
And that is referring to the short term, i.e., 2020. If "what Lynn wants" = Tyrod, then it is not only hurting the team in 2020, it is also hurting the team beyond 2020 IMO. Herbert just showed he can play at this level. Given that, the best thing for the team's future is to give him reps so they can see if he is their legit QBOTF. They know Tyrod isn't.
