what is the difference between AXI DMA and AXI Memory mapped to stream? which one should be used to send data from Zynq to stream FIFO as both can be used for this task

The AXI DMA IP is the general-purpose, high-performance IP one should use to move data between memory-mapped devices (e.g., BRAM and DDR), or between memory-mapped device and AXIS stream interfaces.
The AXI MM-to-Stream IP is a specialty IP designed to encapsulate entire AXI MM transactions and move them over an AXIS interface (e.g., between two FPGA's). It's a way to 'extend' an AXI MM interface, without requiring all of the (possibly hundreds of) IO pins.
