Here's a link that kind of describes the different tiers from different manufacturers:

There are some balls that aren't mentioned in there but generally balls in the same msrp range are about the same.
I kind of agree with the other poster. Where in the higher quality balls it's more for gameplay and some things for every day use might not be what you're looking for.
For example I think the Select ball is often regarded as a great ball but doesn't hold air that well. Where most people only care about it holding air long enough for a game. But personally I want a ball that can hold air for a couple of days.
My kids started out with the Nike Pitch soccer balls, which is the lowest tier maybe second to lowest, that we randomly picked up from a discount clothing store. And they served their purpose pretty well. They did become lopsided and started to burst at the seams. But given how many seasons my kids played with them, we don't really have any complaints.
Due to that and expecting our kids to play more, decided to move to the next tier up with Nike Strike and Adidas Training balls to see if it makes a difference with durability. The feel of the surface is a bit different with some padding compared to the vinyl feeling of the Nike Pitch balls. But jury's still out for us if it's worth it or not.
A couple of weeks ago, and it's pretty common, you could find balls for sale for up to 50 percent off. So the normal price range I look for the balls is about $10 for the Nike Pitch or Adidas Club Balls, which I skip. And about $15 to $20 for the Nike Strike and Adidas Training balls. And we got an Adidas League soccer ball for $20 but I think it might not be suited for our purpose.
As others mentioned you have to consider the purpose, player and level of play when choosing a ball. And for team practices, balls are usually grouped together and the player might not even use the ball that they brought. And there's a risk of the ball disappearing in games or practices from things like getting kicked out of bounds and not being able to find it afterwards. You kind of have to have a mentality to be ready to lose a ball. So I'll probably try to stick to close to $15 for a ball.
So to me $50 is a really nice and expensive ball(I know they get more expensive then that). And if money isn't really a factor and it's a one time cost you won't care about, I'd just get a $30 ball off the shelf and include a ball pump as well.
