I guess the answer really depends on a lot of things.
First would be your playing level and prior experience with other rubbers.
Next would be a more specific description of what you want to achieve:
- do you value a stable push over aggressive backspin, or speed?
- do you want to use this rubber for more than just pushing?
- do you push over the table, or do you often step back a bit?
- do you prefer a tacky experience or a grippy one?
And also, what would be your budget?
There are plenty of options, ranging from classic "Euro" rubbers without tensor, to hybrids in all kinds of hardness and bounciness, to tacky options. Some will work better with a flexible 5ply, others will do great on stiffer, harder blades...
