997H vs 997R vs 997S vs 997?

I can see the silhouette and midsole differences, but Im wondering if there are any overall fit differences between these?

Looks wise I slightly prefer the 997R and more athletic 997S. But it seems like the 997S isnt actively produced? I would love to get the MiUSA 997S Marblehead but prices are high.

The 997 is at Joes NB outlet for around $115. But many say its pretty uncomfortable.

Any thoughts on these?
