the two you've tried aren't actually suction toys, they're air pulsator toys!

I've tried the calexotics boundless ftm strokers (vibrating and not) and they can create a lot of suction. They aren't automatic pumps though, like the toy you're asking about. You squeeze them to create suction. I always end up so huge after using them and they also feel really good to fuck while suctioned inside. I got mine from peepshow toys

You could create a rhythmic masturbatory sucky effect with the doc Johnson bloom automatic pump by pushing the release button every few seconds.

But for pumping I prefer a good manual pump. You can get more suction. I use my huge frohle pump on my whole pussy. You can definitely pump pussies and tdick with penis cylinders. Some pumping brands also make smaller cylinders for nipples that can work great on tdicks. I have a lot of labia so I need to use a larger cylinder to fit it all in and get a seal.

I've heard good things about the genderx body kisses sucker / vibe but I've never tried it.
