Basically, I look at it this way. There is a ZZF2L and Fridrich F2L. I don't care much about last layer since I use OLL+PLL for last layer no matter what method I use(except corner first and Roux). This way we can at least have a better comparison.
For me it takes me around 9-14(or more) seconds to do the F2L with ZZ but I do 5-11 seconds F2L with full Center+4 Slots. For me I think it's not worth it for me to use the ZZ method because the last layer I still use OLL+PLL when it is much more rewarding if you use CLL+EPLL due to the fact that the edges are already orientated thus giving you easier PLL algs(for those who do their edge perms fast). If not, you are wasting precious seconds during the edge orient. But at the same time, you gain it by not regripping even once.
Basically, what I'm saying is, ZZ is a nice method with some flaws if you are not a master in it(like me). Fridrich though is more of a beginner friendly method since you don't have to understand things like "How to confirm that an edge is orientated". That allows people(including me) to get great times even though you're not that great at cubing. Like me I still can't seem to consistently sub-1:10 on 4x4 even though I'm quite fast on 3x3 while some people can get sub-1 on 4x4 when they are a second slower than me.
In conclusion, ZZ is great if you are willing to spend a whole lot of time.
