Which MT switches support RSTP with SwitchOS?

Hey. Excuse me for newb question. I searched all over the official and unofficial manuals to find out which exact MT switches have RSTP in SwitchOS but without any luck.

I am curious about
https://mikrotik.com/product/crs320_8p_8b_4s_rm
https://mikrotik.com/product/crs326_4c_20g_2q_rm
https://mikrotik.com/product/crs520_4xs_16xq_rm
https://mikrotik.com/product/RB260GSP
or any others from https://mikrotik.com/products/group/switches

Could anybody provide such information?

Additional question - what are the drawbacks of using RouterOS on switch devices instead of SwitchOS?

Thank You in advance.
