It can be both, read about this tonearm.
"Another Reed 3Ps innovation is its bearing system. Although tonearm bearing system can be considered as gimbal, it acts like unipivot one. However, major difference from unipivot system is that instead of a single pivot three pivots and both vertical and horizontal axis’ magnetic stabilizers are used. Such bearing system is as rigid as gimbal, but its friction coefficient is as low as in unipivot."
