You can't compare as Klopp would need to be at Liverpool for the same amount of time as Wenger, no one knows what Klopp could or couldn't have achieved if he stayed for another 10 years.
You could compare Klopp and Wenger to their 1st 9 years at Liverpool and Arsenal.
Klopp = 5 trophies, 1 Champions League, 1 League Title, 1 FA Cup and 2 League Cups not including 1 World Club Cup, 1 Super Cup and 1 Community Shield
Wenger = 7 trophies, 3 League Titles and 4 FA Cups not including 4 Community Shields
Although the Champion League trophy is the most glamorous/prestigious European club competition to win, it is a cup competition being the best team over 13 games. The Premier League trophy is being the best team over 38 games.
