Hi Mattias, Thanks for the mail. I don't know much about the other services, but know a bit about MLS. Here's my thoughts.

I've been keeping an eye on MLS for some time now. The data is crowd-sourced by users of Firefox OS devices, users of Firefox Browser on Android [1], and Android users who install the Mozilla Stumbler app [2] & remember to keep it open while travelling around. With Firefox OS on phones dead, that only leaves Android Firefox Users (who opt-in) and users of Mozilla Stumbler. That's quite a commitment for Android users with no direct benefit to them, which I suspect - combined with the lack of Firefox OS devices, contributes to why there's a low number of people contributing data to MLS [3]. I've been a Mozilla Stumbler contributor for well over a year on Android devices. I've noticed that in the last month a very small number of people submit data. A total of ~360 people *world* *wide* have run the apps and contributed data, and in many countries there are very few contributors. Columbia for example has two contributors who have amassed only 22 datapoints between them. I've managed to get to position #2 in the Czech Republic and #37 in the USA on the official leaderboard [3] despite spending only 7 days in each country since the leaderboard was reset mid-April. With a low number of people contributing, the data will likely become stale / inaccurate. So I'd caution using that database in particular unless it can be proved the provider has long term plan for keeping the data up to date and accurate.
