Ball valve throughput?

lets say you have 3/4" copper pipe. a ball valve should have a 3/4" opening in it? ie no reduction in the diameter?

I've seen some ball valves with smaller openings that the line connecting to it. Those are just cheaper ones and I'm not looking at the quality ball valves? OK, what I'm thinking is ones for garden hoses / the splitters. 5/8" garden hose and some smaller ball opening.

'Real' ones for the house have no restrictions?

Most ball valves are full flow.
If you need maximum flow you can purchase full flow valves.

it's a need vs. want?

Full flow valves - that's a gate valve from what I am seeing? Interesting - a multi turn device... so if you don't turn it enough, you have a blockage worse than a ball valve? For things coming into the house you don't want to start adding a restriction right there. So I guess it's a need. Would you know if they;re substantially more money typically

My apology.... I put gate valve when I meant to say ball valve. I edited my post.

Those fittings in your pictures are generic valves for outside watering use.
