Do I need to replace all 6 coils when only one cylinder is misfiring?

if I just need to replace only one, can I use different brand? or do I need to use matching brand?

Only replace which one is misfiring, and I had three different brands in my car at once but fyi Bosch are the most durable imo. The delco rip and get stuck on the plug and then if you don't have the know how and tools it's a mini panic to get it out. Are you certain it's the coil causing the misfire?

Yesterday, i moved coil from 5 to 3. Then I deleted the code. I just need to test drive for couple of miles with wot to see whether the error follows or not. If it doesnt follow, I will assume it's the spark plug problem....

Could've just been a bad seat on the plug. Just keep driving and checking. O Reilly sells Bosch coils but they're expensive.
