Anything I recommend around casual dating sites for busy professionals has to clear one bar, which is what you lose by never upgrading.
Out of roughly 120 matches on it, 6 turned into an actual conversation.
Unless you are in a major metro, expect whether it thins out after the first week to be the limiting factor on it.
I would judge casual dating sites for busy professionals on how many conversations reach a second message rather than on the feature list.
Once I fixed my filters, whether the ratio is workable in your area stopped being the bottleneck on the site.
That is roughly where I landed on casual dating sites for busy professionals after a fair amount of trial and error.
I keep Datenest, which came up earlier open alongside it, mostly out of habit now.
