I know what you mean, but when an entire club/sportswashing project has unlimited funds and is designed and set up specifically for you (even before your arrival), then the two jobs simply aren't comparable. Liverpool have constant obstacles and limitations. City do not. Guardiola has had every possible advantage at all times, while Klopp has had to dig deeper than he ever has just to get close to competing.
If a clean cyclist was pushing themselves above and beyond their normal level to compete metre for metre with rivals who were doped up, they'll also probably be far more likely to burn out or break.
Add in the fact that Klopp has been managing for quite a bit longer (again, always competing at a disadvantage), whereas Guardiola has already had a one year sabbatical during the 12-13 season, rather than doing the job pretty much non-stop for 23 years.
Plus I think most of us would agree that Klopp is a far better, more rounded human than Guardiola - part of him deciding enough is enough now is because he needs some of the "normal life" stuff that Guardiola apparently doesn't.. Klopp knows that all those times with friends and family that he's missed are as important as anything he'll do in football. Guardiola is probably way more of a narcissist bellend and workaholic to really care about putting other parts of his life first
Ok, some of that last one was just a dig, but fuck Guardiola 
I was going to reply similarly yesterday but didn't have the time. I'm not surprised in the slightest that Ped has outlasted Jürgen in the PL. They are two completely different characters. Jürgen has incredible self and wider awareness. He isn't a narcissist either, unlike Guardiola.
Their working environments are chalk and cheese, too. Klopp is at the top table through sheer hard graft. Guardiola is there by having every conceivable advantage handed to him on a plate. Anything Guardiola says he needs, he gets. One man is a lottery winner who doesn't have to worry over anything. He can instantly access anything he feels he needs. The other works for everything he gets. The difference is monumental.
The toll taken out of a person doing it naturally, like Klopp, is vastly different to the toll taken on a man like Guardiola, who is basically sitting in an ivory tower playing fantasy football manager with the wealth fund of an oil state. Jürgen is working, whilst Guardiola is playing.
If Jürgen was an egotist he would probably stay at the club and drive himself into the ground trying to put a stick in the spokes of football's Lance Armstrong, but he's not, so he knows when his well-being is being compromised. He knows when to call a halt and protect himself, his family and his club. He's a hundred times the man that Guardiola is.
So yes, it's no surprise to me to see Guardiola outlast Jürgen here in the PL. He's no better though. In fact, of the two, Guardiola is the inferior man and manager. Klopp has worked for every ounce of his considerable success. Guardiola can never say the same. Of course, he's a good manager, but he's been gifted absolutely everything. Gift wrapped, with a big bow on the top. While Jürgen has been working, Guardiola has been playing. That's the difference.
