Abec isn't a brand you morons, it's a rating system.
I've skated a few Rush Abec 5's before, they were really smooth bearings but they didn't last as long as some bearings I've had in the past.
The only Blind Lifetakers I know of was a series of wheels they brought out about a decade ago, and they were horrible haha. If they are now doing bearings under the same name, I haven't tried them out.
However Dwindle products (Blind, Almost, Enjoi, etc) have been great quality recently, so they might be worth a try.
I'm sorry that wasn't much help on your decision, but with a lot of things in skateboarding, you have to try them out for yourself to see if you like them personally, as different people like different things.
I personally skate Bones Super Swiss, they are expensive but a set usually lasts me about 2 years, so they are worth the money in the long run.
