I wouldn't restrict myself to a choice of two lids, as good as those two are, have a look at several and cross reference them to their SHARP ratings if you find a comfortable one.
I'd recommend at least a look at a Bell Race Star Flex DLX, for me it's the best I've ever had in terms of comfort, features , quietness, ventilation, build quality, design / looks .... and that photo reactive visor. Oh, and it's a Bell.
On the visor, the darkening / lightening doesn't react quickly enough for the first 100yds of a tunnel, but after that fine, you need to be aware of it that's all. The massive advantages of a legal dark visor that'll get you home safely after the pub at night is enormous.
