I've used both. I like the pressure bleeder much better.
Trouble with vacuum bleeders is that you have to really make sure you have a good connection to the bleeder screw. If you don't you will suck air into the hose making it hard to tell if the bubbles are in the brake system or are coming in around the vacuum hose.

I have a vacuum bleader and have only used it once because it sucks. Air is drawn into the clear hose, and it is difficult to tell if the air is coming from the brake line or being sucked in from around the nipple. I now manually blead my brakes, although I would like to have a pressure bleeder!

I have a vacuum bleader and have only used it once because it sucks. Quite literally. I have used a vaccum bleeder, it is really difficult to tell where the bubbles are coming from, but if you are patient you will get a good pedal. Just to be safe I will have an assistant (spouse/son) help with the pump and hold after I'm done.

I guess I should have ask before buying the vaccum bleeder. The package says that it can be used to test other stuff. Is it worth keeping for the other stuff??

Manual bleeding pushes fluid out. That sold me on the concept of the pressure bleeder. With the Motive, I can bleed the brakes with the car flat on the ground, wheels on. My 11-year old can flush and bleed the brakes and clutch with the Motive bleeder and a litre can of Ate Blue.
Also, I have never seen a pro mechanic pull out a vacuum bleeder to do brakes. Seen plenty of pressure bleeders come out for the job.
If you get the Motive, find a large syringe like the kids use at school for science (50-100ml). When you finish, you often need to pull a bit of the fluid out of the reservoir to get the level right. The syringe is the hot set-up.
Wear glasses or goggles too. Often overlooked, an unexpected spray of brake fluid will derail your 20 minute project.
Usual disclaimer... No commercial interest, just a pleased user of the product.
Good luck,

I have a pressure bleeder for my race car. One of the best tools I have. After each day at the track I have found that I need to bleed the brakes. If I don't the pedal is just a little soft and I feel like I do not have good feel for the brakes. Maybe a little overkill, but to me well worth it to have confidence in my brakes.
Anyway the pressure bleeder makes the job a snap. I have done it both with the wheels on the car in the ground and on jacks stands with the wheels off.
I can't imagine bleeding brakes the old fashioned way...
"Ok pump it up.... Hold it"
"Ok closed.. Pump it up"
"No hold it I screw is still open!"
"Ok here we go again!"
"Pump....

Have not tested a vacuum bleeder.. but my pressure bleeder works fine, even with the nasty clutch.
