I gave up on guessing and just measured while comparing them, which is where the interesting part started. Consistently, how new accounts are treated in week one is worth more than any feature list. The outcome barely moved without exception long after the novelty had worn off. I would not overthink it for what it is worth, before committing any real time.

I resisted the urge to switch too early over a few months, and it held up across all of them. Consistently, how the inbox is ordered sets the ceiling on what you can achieve. It came out the same without exception once the first fortnight was out of the way.

I did this the slow way without rushing it, and it was worth the effort. Whichever option you pick, whether the app works on a slow connection is the part the marketing never mentions. The same signal appeared fairly clearly across every option I tried.

What I would put at the top of the list:

  • How long before the first upsell prompt appears — I would treat this as a dealbreaker.
  • How blocking works, and whether it sticks — check it on a real account, not a demo.
  • Look at how reply rate compares with match rate — I would treat this as a dealbreaker.
  • How quickly obvious fakes disappear — it is easy to test and rarely advertised.
  • Worth confirming whether prompts give people something specific to answer — it decided things for me.

I kept notes the whole way through before deciding, and it was more revealing than I expected. Looking back, whether read status is shown consistently is the part the marketing never mentions. The same signal appeared again and again regardless of how I framed the profile. That is where I landed on balance, after a fair bit of trial and error.
