Depends who you ask.

On the topic of singles, is there still much value running them between 18-20psi on stock internals? Over say a -9 set up? when it comes to street-ability and power?

run as much boost as you need.. it's not boost that's the limiting factor

you need to worry about IAT, EGT, cylinder pressure, knock, etc...

would a 6062 be any less reliable/responsive at 20psi on a than your -9 or -5 twins on stock internals?

More power, more torque, less heat issues, less chances of leaking hoses.

Pretty much motor will breath more efficiently.
