One data point: LTE gives me 65-90ms ping RTT in reasonable non-crowded indoor conditions. Subjectively, working interactively via LTE is totally fine for me. Compare that to UMTS (3G T-Mobile DE) where I think RTT was more like 350ms and working interactively is a pain.

Anything >10ms can be noticeable if you have a lot of requests or symmetric applications.

But I find reliability the far bigger problem with LTE than performance if everything goes right. Not sure how 5G will perform there.
