Which ball valve is better?

Both have the same spec's. Same brand, same size, but one is $1.30 cheaper. Is price the only difference? Is the cheaper one a older model?

Valve 1 Rona
Valve 2 Rona

Both items say:
The John L. Schultz "Aqua-Dynamic" non-shock WOG 1/2" solder full port ball valve is fabricated with no-lead forged brass and features long-lasting Teflon seats and a comfortable red vinyl handle. The easy one-quarter turn fully closed- or fully open-position straight galvanized handle provides full flow, delivering 150 PSI WSP steam and 600 PSI non-shock WOG at -20°F to 350°F temperature range. Threaded ends comply with ANSI B1.20.1, solder ends comply with ANSI B16.18, and the valve is CSA certified.

1197-803 is standard port
1197-503 is full port

I believe standard port has a small diameter inside than a full port. I am not a plumber so no idea which is better, I just know full port will have better flow.

Yup - the difference is the more expensive one has a drain on the non-pressurized side. Those are ideal for lines going to an external hose bib.

I would pay the extra $1+ for the one with the drain port. One day, if you need to replace it or want to drain the whole house's pipes, that $1 would be money well spent.
