Done. Again, extremely vague conclusions against stealth. How does it fare against the B2 for example? Or F-22?
Vague of course due to the intensely classified nature of the beast. RCS data typically requires a Top Secret clearance and need to know. Vulnerabilities are most tightly held, so no way could someone knowledgeably discuss comparisons in a public forum without violating the law.
That said, you can figure the advances in stealth since the F-117 have addressed the weaknesses, either with technology or tactics or both.
