I thought it was interesting that Rips' reputation is good with certain heroes and not so great with others. So far the Johns' Rip Hunter has positive remarks from : Zantanna (who met him before), Ollie (AU Ollie but he wasn't going to question someone with such a great rep), Waverider in 52 (ironic considering TMVP), Chronos 2 (Walker Gabriel), and Red Robin.
Of course he also has people that aren't thrilled with him like the Linear Men. Superman (who dislikes time travelers in general), and I honestly can't tell if Hal didn't like him since he was more concerned with messing with Booster. But when Johns was writing JSA he started shaping time travel and the character. When the first Hourman goes to Ray Palmer of all people for help and this is what he has to say:
Just to clarify: Ray's archenemy uses time travel, Ray uses a time machine called the time pool, yet he doesn't understand time travel himself. He admits this and yet he dismisses a guy that's called a freaking "time master" as unqualified? Oh yeah, and guess who shows up in like 6 issues to save the JSA because they ended up screwing up the mission and nearly getting themselves erased? Just like dad, no one gives the Carters any respect.
