The +2 strength is good, but cut block is about as useless as it gets for SAs, and I should know because I got an AEQ piece and have 9 cut block on one of my Cs. I took it because he has 100 agility. However, per Q&A
1. Cut block only fires if you are about to get reverse pancaked
2. No attributes effect the efficiency
&
(already known but not in Q&A)
3. The DL counter is agility, and most DL have over 100 agility at high levels
The 5% HBC is great, but the +2 blocking is kind of meh since your blocking will probably end up high enough you don't need any equipment in it
If you are determined to chose 1 of those, take the 5% HBC
