Is it worth getting the Makita track saw if I have all DeWalt stuff?

I'm on dewalt because my first boss gave me his old stuff when he retired. I have been slowly upgrading and have a mix of old and new all 20v.

I really love Makita and the 40v xgt track saw is on sale. Seems to be much better than the DeWalt one.

Is it worth getting some 40v xgt Makita stuff and having a mix of 20v DeWalt and 40v Makita? Or do I just go for the DeWalt track saw?
