I find Understanding the differences between garmins many different units a nightmare , but am considering the 450s as it appears to have all I need and the screenshots of the 3d views look fantastic , especially where it shows land and sea bed etc as a sort of 3d cross sectional view.
How necessary extra the 3d charts are and what they cost etc is a mystery
The 450 is the chartplotter, the 450S is the S
550 is same but bigger, 550S is bigger screen + sounder capability.
555 models have higher resolution (640 x 480) screen but same size as 550.
You need to add transducers to the 'S' models. You can't retrofit sounder capability to the standard models.
The 3D mariner/fish eye and aerial views are part of the g2 Vision cartography. The base sysems just includes the standard BlueChart mapping.
So if you want those features, you need the g2 Vision card for whatever area you're cruising. A 'small' chart area will be around £150 but that would cover eg Bristol Channel, Devon, Cornwall & S Wales. Regular @ around £220 would give you whole of English Channel and N coast of France.
They all have internal antenna by default with a connector for an external antenna if that doesn't work for you. Ext antenna around £40.
The Garmin website shows chartplotters
but I agree it's not always clear what you need.
