The # of missiles issue comes up for several reasons. One is that Mr. Sukhoi Rules, Just Look at These Pretty Pictures says it's a big deal because AMRAAM is easily jammed. This Greatest Armchair Military Analyst of All Time came to that conclusion because information about crosseye jamming has surfaced in open sources and the latest Sukhois have big wingtip pods. The T-10 series can carry lots of missiles and since the T-10 is sooooo much better than the F-35 and the T-10 carries more missiles than the F-35 than lots of missiles must be good. The Typhoon carries more missiles than the F-35 so the Typhoon Fanboys constantly play up # of missiles. Note that the Gold Standard of A2A, the F-15, carries 4 BVR missiles. I am under the understanding that fuel capacity is more an issue for the number of engagements that can be carried out than # of missiles. Once the USSR fell sheer numbers of enemy air isn't a big deal so I'm not sure where this focus on # of missiles comes from. The most interesting thing is that all it carries is AMRAAM. That would be a more interesting topic to discuss.
So the F-35 ultimate stealth missile loadout is 6xAMRAAMs and 2xASRAAMs or just about exactly the same as the F-22.
The F-22 can give its missiles more of a running start however.
