What is the best size tank to get under 30 US gallons and why? Thanks!

The bigger they are, the easier they are to care for. Are you trying to do a nano tank or what?

Depends on what you want to accomplish. There are any number of all in one cubes, and rimless tanks under 30G if you want something more dramatic than a standard tank. Fluval's nano line comes to mind for some wild looking stuff. The 20L is a nice long low shape great for high light on the cheap. That said, some of the nicest tanks I've seen have been plain ol' AGA 10 gallon cheapies.

Well right now I have 3 tanks. Looking to get rid of my 55 and 5 gallon. My 5 gallon is for cherry shrimp breeding and in my 90 gallon my albino bristle nose plecos are breeding and the fry are outgrowing the breeding net. The main purpose of this tank is to use a grow tank until they become of size to sell or trade in.

Unless 30 gallons is a firm limit, there is a 40 gallon breeder tank. Long, low and wide. The 20L would be a good runner up. You need surface area more than depth.

I'm also breeding plecos myself and have a bunch of 20g long tanks.
For plecos, if you create a tank full of hideouts and caves, they really appreciate it and the tank doesn't seem to crowded cause they are busy attached to something or hiding.

Also, I have a 30g cube tank that it's short but full of room to work with and gives plecos more room to roam around.
Try a cube tank if you haven't already.

I'm a huge fan of the 12 gallon long tanks. They are 36 inches long, but only about 9 inches tall. They make for some very dramatic and beautiful tanks.

20 gal long gets my vote! To me its easier to aquascape.

20 long or a 30 long. 30 long is my favorite tank size if you don't wanna go huge or don't have the room for a 55 or up

As others have said, it really depends on what you're trying to do. My favorite tanks are my 2.5 gallon nanos. They can be put just about anywhere, maintenance takes little time, and I love the challenge of aquascaping something so small.

The 20 gallon long is a nice size tank. Doesn't take up much more space than a 10 gallon, but has more stocking options. Nice footprint for aquascaping, and the height makes it easy to light adequately. The 29 gallon, which has the same footprint as the 20 long, also has pleasing proportions.
