Go with a 90/105 macro lens for reasons that have already been discussed. IMHO, VR or IS wouldn't help macro at any significant levels since one of the major issue is actually back/forth movement that's moving the plane of focus. VR/IS can not correct this. In addition, IF they did manage to design a VR/IS that can keep up with the speed of up/down movement, the gyro and actuator mechanism will need to be so responsive that it will generate vibration itself and drain your batteries in no time.
On the top of that, VR/IS won't assist in subject motion which is also another constant problem in macro photography.
All the macro lens offerings from Tamron, Sigma, Canon and Nikon are all EXCELLENT, you can't really go wrong even if you randomly picked one. Would I? Why not!
