If you are running into spark blowout you will def want to upgrade to better coils NOT just aftermarket sr20 coils as they won't be strong enough.
Check out this article for a full write up on SR20 spark plugs, coils and spark blow out
All of the coils you listed above are great options, i personally use the R35 coils as they are very budget friendly and work great for up to ~40psi of boost.
