I don't have experience with the Rode. If I had to pick between the Apex and the MXL, I'd go with the MXL. The Apex can sound good on quite a few things, but stock it has flaws. The grill is one, the circuit is another, but the major problem is the capsule.
Technically the capsules for the Apex and MXL are made in the same factory, but Marshall seems to be pickier about the quality for the V69.
