Depends on what stimulation you like best. Thrusting= dildo or probe. A presence that's "just there" with a little wiggling = plug. Vibrations = vibe.
The only one of those I'm not a big fan of are the beads, because so often they're a "one shot" toy as they're so difficult to put back in. Hybridize them with a dildo to get a "bead stick" and you're back in business.
