V Brakes

ok I have the front finally down.
Now for the rears, the bike came with V's F&R. the front is now disc, the rears
i'd like to keep the V's (from what I have read) it's not a bad choice, but not the best, that aside which are the better shoes (pads)?
I have come across these brand names so far;

Kool Stop Lightweight Holder Version 2 V-Type Brake Pads for Electric Bikes:
All Weather Explorer XTR Level Alloy Cartridge & Replaceable Pad:
Clarks Elite Mtb Yybrid V-brake Pads With Lightweight Aluminium Holder:
RavX MTB V-Brake Thermafoil Red Pad:
Kool-Stop Dual Compound Mountain Pads for Linear Pull Brakes Threaded:
Kool Stop Bicycle V-Type Holder with Brake Pads (Dual Compound):
Promax V-brake Shoe 3 Color:
BRAKE SHOES OR8 MTB 72mm:
Jagwire Switchback Tri-Zone Mountain Bicycle Linear Pull Brake Shoes:
that is just a few of the mid to upper priced pads.
I have read the reviews but needed some more reliable input that I know i'd find here.
Thanx my fellow MB's.

I like the fact that Jagwire mentioned their compound they use (British Standard).
a lot more reviews on the Kool Stop products.
they are not greatly expensive, but I think one day I will try a few different brands and compare when I get this build done.
had a friend once say "It matters, it's all in the components".
