I have a Freemont Tweed, and a different version of the Mainland tweed (only 2 latches instead of 3). I have seen an Ameritage in person (not sure if it was a Silver one though).
If money were no object, I would get the Ameritage, but I would have to make sure my custom uke fit. I tested out my Kanile'a Super Concert in one, and it didn't fit. The Freemont Tweed (rectangular box) will fit more shapes and unique sizes of ukuleles, but they smell strongly of glue for about a month when they are new. I returned my first one because of a QC problem with the tweed fabric weave. My replacement one was fine though. I know someone else who just got one, and the latches were hard to close on it. If you get a good one, and air it out, it is pretty sturdy. The Mainland-like tweed case I have is very nice. Lighter weight than the Freemont, and very nice looking. Make sure if you choose this one, that your new custom will fit properly. If the Mainland one will fit, this would be the number one choice if money is a concern.
