I know about Kester/Multicore and such... But these are the solder brands that I can order locally. I can order from eBay or Amazon but due to the high shipping costs, I want to see if some solder is usable from my local shops

.
The solder will be used mainly for soldering SMD components but also for through-hole, more rarely though.
Also, I've seen solders with added copper or silver, but never used them before. Should I consider them?(they are not listed here due to their a bit higher price. If they are worth it, I can buy one)
HQ 250gr - SN60PB40-0,70-250G
Felder 500gr - SN60PB40-0,70-500G
Fixpoint 250gr - Sn60/Pb38/Cu2 0.56mm
STANNOL 500gr - Sn60/Pb40 1mm
Alpha 500gr - Sn60/Pb40 1mm
Cynel 1kg - SN60PB40-0,70-1KG
Please help me choose which one is the best from the list, without regard to the price or weight.
