OK thanks. Which inexpensive laser pointer do you think will shine better?

You could have easily found the answer easily using LPF's search function.

For difference see post #7 by Podo of Sanwu lasers/China here: https://laserpointerforums.com/threads/questions-about-301-and-303-lasers.101099/

Shine better?
They are all generic toy quality/lowest quality, lowest cost mass produced junk lasers made by several factories in China.
What do you expect for about the price of a good cup of coffee $5-$10 retail price on eBay, shipping included.

I mean, if you buy a laser on an ebay, which one will shine brighter red or green?

Green is brighter, watt for watt.

Just keep in mind that the cheapo 303s and 301s are generally all over spec. So you aren't getting something <5mw. Safety goggles are a necessity. Also if you decide to go with a 532nm they usually will leak IR light, which can be dangerous without the right goggles. They are great fun though just keep your expectations low for fit and finish lol.
