There are good and bad bearings. Good ones last a long time and spin freely, bad ones do not. For the purposes of the type of skateboarding practiced by Slappers, there are no "fast" bearings, and any bearing spinning freely will be equivalently fast to any other decent bearing.
I've always described Bones Swiss as the "**one less push bearings".
If you're pushing 3 times on Reds or G3s, you'll only have to push twice on Swiss.
I've never been a fast feet kinda guy, I like to take my time getting my feet in position, so that extra ten or so feet of setup time I get from one less push is precious.
*I guess it'd technically be "one
fewer push bearings"
**One less push does not apply if you're only pushing once on the cheaper bearings, you still have to push at least once even on Swiss
