I'd say it comes down to personal preference.
So far I've worked with both the closed screw and open screw type Monoprice plugs, the Lowe's set screw type plugs, and the Blue Jeans Cable compression type plugs.
For connection to the speaker wire, I like the set screw style (I've connected them to 14 and 16 awg wire), but I think all of the plugs I've tried work just fine. The BJC plugs are a nicer style of compression plug because they have a "slug" insert that tightens down on the folded wire.
My biggest gripe with the Monoprice plugs is that plug end not connecting as firmly to the binding post as others. I think the BJC plugs were the best for this, followed by the Lowe's plugs.
I am thinking about getting some of the Nakamichi plugs since they seems to be just like the Lowe's plugs, but cheaper.
