First and foremost as someone who bred Ameraucana to the SOP blue is a shade that can range widely INcluding hues of green and varies majorly according to individual.. Get a load of the egg color chart used by the Ameraucana breeders club.. from google..

Folks who insist green eggs aren't from pure breeds don't understand the complications of breeding OR the standard of perfection as it's written. Noting shade is darkest early in the lay cycle and can fade slightly towards the end of the season and even a little during the normal cycle.. being darkest the first day or two after day off for example.
To get the MOST striking color out of your eggs.. HAVE a variety for comparison.. white, brown, blue, etc... and carton or presentation color of the container matters also..

Now $3-4 birds are Easter Eggers.. some of my favorite. No two ever look or act exactly alike! Though they may be similar. The blue and green eggs in my examples here are both feed store hatchery Easter Eggers.
Ameraucana.. usually close to $20.. are also good birds.. but usually sold in standard colors.. like blue, black, lavender, wheaten, etc. Good birds, hearty, active foragers. Fun birds, just not the wide variety of patterns. The better temperament for MY preference would probably be the EE/Am.. with regards to hanging out with kids
Cream Legbars.. kinda cute, more flighty or reactive/nervous than EE/AM.. generally speaking not withstanding difference in individual personalities. Sometimes eggs can verge on white.. individual line matters.. LOOK at photos of their birds and their eggs.. sometimes the evidence is right there! I have NOT kept CCL, per your request from prior keepers.
I think I prefer bearded birds over crested.. and I'm not crazy about how cresting wrinkles the straight comb.. but then again pea comb isn't my favorite so.. GET BOTH! Or rather get all 3 (EE, Am, CCL) and decide for yourself!
CCL are tending hyper.. I'd lean calmer.. breed wise.. but some individuals do stand out regardless. And although I prefer more approachable birds.. one Leghorn really showed that they can still be endearing while not being lap birds.
I have ordered from Meyer.. and have really good luck with their shipping. Their birds are decent hatchery quality birds as well as fair prices. I also have gotten
good birds at fair (straight run) prices from Cackle who I think is also offering true Ameraucana.
Collecting blue eggs and others makes me feel like a child again, it brings joy.. It also actually helps to know who is laying or not when you have a variety and easier to identify if anyone is having an issue that needs help.
Many hatcheries are working on hybrids that are able to lay more often.. colored eggs take longer than white to get their pigment layer.. One example would be the Super Blue Egg Layer.. so there might be other blue layer to consider.
Hope this helps a little with food for thought.. your really can't go wrong!
Happy adventures!
ETA: In Boston.. I'd also go with the EE/Am for the pea comb and cold hardiness.
