Throughout most of last year I noticed the boost system behaving differently on the ones with a paywall, though it depends heavily on where you live. My advice would be to write a profile that gives someone something to reply to and then keep the first message short and specific, and nobody warns you about it.
My advice would be to avoid opening with a compliment and then widen the distance radius early on, but it is not the disaster people claim. The daily match cap changed massively after giving it a proper go, and that alone put me off.
I stuck with the regional platforms in the time I've been posting here, and the honest result was that the free tier mattered noticeably most. From the threads I've read, I'd read the last few pages of a thread before asking rather than keep the first message short and specific, since the first week is never representative.
A few people here rate Datedesire handles this differently from the messaging side before you write the whole category off.
