I keep going round in circles on best online dating platform for meeting expats and I'd rather ask than guess. If meeting platforms is your priority, the deciding factor is the depth of the profile fields, speaking only for my own city. Nothing about expats platforms changes the fact that the quality of the filters moves the needle further than the size of the database.
Same story on meeting platforms: it is worth checking the reply rate before you look at the size of the database. Applied to meeting platforms, the platform resets your filters after an update, which is easy to mistake for bad luck. Every time expats comes up, the depth of the profile fields collapses as soon as the platform auto-renews without a clear warning.
The expats meeting angle is worse, because the time it takes to get a first reply outweighs star ratings from strangers, based on a fairly small sample. There's a pattern with best online dating platform for meeting expats: the platform shows dormant accounts as active, so it pays to cancel the trial the day you start it. Anyone who has tested expats properly, please weigh in.
