Need to replace my grey 990v5. Deciding between the 997 vs 998 vs 990v4 vs 993 vs 990v6 vs 991v2

My trusty daily beater 990v5 is starting to get holes in the upper, so unfortunately I’m looking to replace them.

I live in Australia, so these shoes all retail for roughly the same price. With that said, 997 is unlikely to be on sale any time soon since it just re-released.

I like the 990v5 a lot so I’m thinking of going with the safe option of 990v4 (since it seems like the nearest alternative), but I’m open to hearing other people’s opinions
