No one can say what's best for your application, but I can offer what I have experienced to be the pros and cons of some of them.
Disclaimer: I do my own wiring, so I don't care about ease of installation.
Blue Sea: Reliable, versatile, indestructible, but large. My favorite when I have room for it.
EB PC8: if you want plug-and-play, go with this one plus the EB harness. Pretty hard to screw up. It does not really handle 12 ga stranded, despite what it says; and it relies on solder for mechanical strength, so will be more failure-prone over time than will the Blue Sea.
Fuzeblock: Handy configurable switchability of outputs; unfortunately, has all the disadvantages of the PC8, plus a relay that can't be field-replaced, which is a dealbreaker for me.
I have no experience with the Centech.
I am currently using the PC8 with my own wiring.
