I am good with either and have both. They are both STRONG. For the B&T you can use SIG, B&T and GLOCK lowers. I chose SIG lower for my APC9 and have never looked back (I don't own a single Glock and will remain Glock free). If I had to choose one, I am sticking with my B&T. I love it to the point I have the B&T APC300 SD SBR (whisper quiet 300 blackout), APC 9 Pro, APC9 PRO SD, and APC10 Pro.
I'd choose neither, because both are way too expensive for a semi-auto 9mm. Those aren't subguns (which is short for submachine guns), they're big pistols that are cosplay subguns. Now, the real thing? MP5 all day long. For semi-auto, I'd save some money and buy a 5.56x45 like a Tavor X95.
I’d pick the HK SP5 for looks, performance, application, and the long and impressive history of HK.

Both are awesome

If the zombies come, you're not going to be able to backyard repair and upgrade 2020's(edit 2010's) technology as easy as you are 1960's technology.

HK SP5 100% is better, because it's a roller locker and not slam fire.
