I'm not sure how much you're willing to spent on a camshaft. I do know Melling makes a stock spec for 22re motor and a buddy of mine installed one last year after having issue with his OE one and ran fine. Melling part number is #TSC-1 and sells for about 100buck at most local part stores.
TRD stage 1 is very good from those who used them I heard. Only downfall, TRD stop selling the camshaft. I'd searched and found out the Crane Cam is the manufacture of all 3 stage TRD camshaft. For the Crane Cam part #704-0010 is identical grind to TRD level 1 spec and is still available to order online, sells for about 215ish.
Friends I know with 22rte and 22re who used both the Crane Cam 704-0010 and DOA C270 camshaft say DOA is 3x better with more torque and power.
DOA price is 185. I spoke with Tim at DOA and these cam are new CWC blank and DOA grind them to their spec.

LC also sell camshaft as well but not much feedback on their. I read somewhere that LC sell repackage WEB camshaft, but I can't for sure prove this. Hope this help...
Here is a comparaison chart I found useful on cam spec.
