Clipper and Viking are identical except for the name and interior color scheme. They label them differently in order to provide dealers exclusivity in the lines. (2 dealers close to each other can’t both carry Clipper but one can carry Clipper and one can carry Viking).
A BHS, however, will have a slide where a BH will not, so whether you want that or not should make your decision. Keep in mind that the slide adds weight, too, so make sure your tow vehicle can handle it if you go that way. Don’t trust the dealer, read up or ask here
