Oh, amazing, this level of detail :-o

If you search on www.cisco.com for "SXH3 release notes", you should find
a (very very long) page that details all the new features in SXH as
compared to SXF.

I'd go for SXF13a or SXF14.  Those have been very reliable for us.

Regarding SXF15, there have been "interesting" reports on this list.

SXH3a has tons of new features, many of them are quite cool, but I'm not
sure I fully trust it yet - SXH3 has bitten us with a nasty BGP bug (which
is fixed in SXH3a).  See the page mentioned above if there is anything
you want/need to have - otherwise, I'd stay with SXF.

(SXF5, on the other hand, has memory leaks in BGP, if I remember 
correctly... :) ).
