Nothing significant between -4 or -5 Fury cost for HOTA from SOJ. Taking 100 stock Max fury into calculations for example:

100 max fury / 16 fury per HOTA (by using -4 fury from SOJ) = 6.25
100 max fury / 15 fury per HOTA (by using -5 fury from SOJ) = 6.66

Both -4 or -5 SOJ will average out around 6 HOTA frm max fury. As long as you're getting -4/-5 for HOTA SOJ, you're good and should be able to spam HOTA and maintain WOTB relatively easy. That being said, aspd for OH best to be at 2.8 breakpoint and critical chance should be above 60% after WOTB disregarding follower's buff if you're running WWHOTA build. Goodluck and have fun spamming hammer all you HOTA barbs
