Should mwd49b be avoided?

I just picked up a SW3, and upgraded it to MEC24H. So far, I am pretty happy with it. I'll get a full day out of the battery, and that was with the just got it fingers playing with it more than I normally would.

I've heard some bad things about mwd49b on our watch, my watch keeps asking me to update, should I just avoid the mwd49b update for now and stick with MEC24H?

Thank you!
