Current 'best' aftermarket non ac heater core?

BTW. Sorry , I know this is off topic but Spectra also makes a great tank sending unit. I have one, with a 1/2 inch outlet.

Very well made, works perfectly with factory gas gauge and lock ring is same as factory with no sealing issues.

Been in my car now for over almost five years. See below.
