Main shutoff valve type before and after the meter

I'm planning to replace the both shutoff valves before and after the water meter, from my understanding, it will be a ball valve. Is there any specific type/model/brand to recommend? Does it require a drain port on the valve?

many thanks!

Make sure to get a full port ball valve.

I've never seen a shutoff AFTER the water meter? is it to prevent the water from backflowing to where you are working if you are doing a meter swap? seems like its not really necessary, no?

Does it require a drain port? any reliable brand to recommend? Thanks a lot

I wouldn't put in one with a drain as I would solder in a tee and install a sediment faucet instead to act as a drain.
I have no idea what they sell in stores now but don't buy any offshore cheap crap.
