By 2020, only 187 of those 1,100 "most advanced" fighters will F-22s, while the other 913 will be F-35s, many of which will be Navy and Marine variants.
By 2025, out of those 1,700 "most advanced" fighters, only 187 (or less depending on training losses) will be F-22s, while the remaining 1,513 will be F-35s.
The F-35 is only front aspect stealth, and as a strike fighter, it cannot dogfight it's way out of a paper bag against a good 4th generation fighters such as the Su-30, let alone the PAK-FA.
The air environment is very electronic, networked, and skilled operator/support intensive. I don’t really think it matters, if the Russians had the Raptors, and we didn’t.
