The EF 135mm f/2.0L is a special lens, IMO. While the RF 135mm f/1.8L IS may technically be "better", I prefer the rendering from the EF lens, and it seems others agree. This lens was recently voted as the best EF lens of all time by social media followers of Canon Rumors:
Unfortunately, as an older EF lens introduced before 2010, it does not support high framerates on Canon R bodies. Shooting speed will be limited to about 7 fps or so in H or H+ modes. See here for a list of EF lenses that are compatible with high-speed shooting:
In terms of actually following focus at whatever framerate, the 135L is a very fast and responsive lens, leaps beyond what you are used to from the RF 85mm f/2.0 IS STM Macro.
