Team Tier

Just be prepared for different locations to also have those names that might not always be super accurate. For example, UFA Norcross Premier is rarely as strong as UFA Forsyth Premier. Tophat Milton Gold is sometimes as good as Tophat Gold from Buckhead and Tophat North Gold. SSA Blue is their main location so usually has the strongest teams, but not always. The above is for girls. Boys have some differences.

You will get it with time and then as the year goes on you will start to be able to tell based on the athletes on the field and the skills they possess.

Smaller clubs also have levels that vary widely between ages and genders even on the "top" team.

Youth Soccer Rankings used to be fairly accurate at ranking teams, but that seems to be gone. SincSports is far less accurate. If anyone knows of an updated, accurate reporting system, I’d love to know about it.

usarank.com is decent

I was just tinkering with it. Not bad.

You forgot Champions, and National.

I'm curious as to why it is still called the Big 5 here in Metro Atlanta. Aren't there 7 clubs with ECNL or GAL on the girls side? I don't know the boys side as well, but I'm thinking it is similar when looking at ECNL & MLS Next???

TopHat - GAL
SSA - GAL
AFC Lightning - GAL
Concorde - ECNL
UFA - ECNL
AFU - ECNL
GSA - ECNL

Am I missing any clubs?

Encourage your child to play at the highest level they can, within a reasonable distance from your home, where they have friends, and the coach doesn't hate them. If your child is exceptional, give them the opportunities you can. High school is the pinnacle for almost everyone; they will love it and carry those memories for the rest of their lives. Do not chase ECNL or RL or Next or whatever.

Life skills and friendships can be earned at SCCL-C or P2 or ECNL. This will be a shocker; all leagues provide equally meaningful games for the player. Outside of friends and family, almost no one cares about the results of games (even ECNL). The only time anyone in Georgia cares about the result of a soccer game outside of your immediate family is probably high school playoff game.

College soccer is overrated for most. Over 30% of kids quit their first year, and most kids are probably going to a D2/3 with 30 other kids on the roster and little or no scholarship money. Tell your kid to join a club team in college, play intramurals, join a coed indoor team, go out on Friday/Saturday and live your life. Unless they really really love it that much... just don't make it about you.

The problem with youth sports is there is always a new 8-year-old scoring 10 goals a game in rec and their parent thinks they are special, they enter the matrix. They don't know; they don't want to know. They don't want the red pill. Many of us have been there. 

Not possible. They don't post scores for those age groups because the games are technically "friendlies." There are no leagues so no standings or recorded scores. Sincsports used to track those IF the TM decided to post them. Gosport might again IF the TM posts them. In reality no one cares about those scores except maybe the parents on those teams.

If your goal is to find out who are the best teams/clubs near you then your best bet is to ask here and you will get some info to digest. Then you can go watch the teams play.
